  1. I cant say I have ever tried it on W2K8 but i assume it would be the same except for the server's firewall.

    I would try this:

    1) VPN to the server internally with no server firewall

    2) Turn on server firewall, get VPN working internally

    3) configure external firewall

    4) Test VPN externally

    5) check firewall logs & repeats steps 3&4 as many times as needed

    Although im sure you have tried all of this its worth a go, I think this pretty much covers everything :)

  2. It's rather unlikely to be a RAM problem, but I'd still run memtest86+ to check it anyway. Ideally you'd check the RAID card's RAM too but that's a little trickier.

    First thing I'd do is check the SATA cables (and make sure they are the locking kind), and making sure I have the latest firmware on the RAID card along with the latest drivers for it (and Windows fully patched of course). There's also still the possibility of having one or more bad sectors on any of your drives (don't rely on SMART to let you know). It also could be caused by any piece of software that interferes with disk I/O, like an antivirus (or even malware).

    There's also the possibility that the error ID 55 isn't actually a "real" problem as seen here. It would also help knowing more about the particular problem, like if there are any other errors logged around the same time.

    There's a lot of possibilities which are FAR more likely than "my RAM flips bits randomly a billion times more often than it does in any other computer", and I'd say the odds ECC would fix any of this are right next to none (I'd bet good money it won't fix it)

    I have run Memtest 86+ for 12 hours on the server and found nothing. The Card originally had 256mb ram and still gave me the errors, I upgraded to 1gb in the hope of eliminating the issue but I still get the errors So I think I can say the Card's Ram is ok.

    I am considering a reinstall anyway so now might the time. With regards to drivers for the card I have a choice of Storport or Scsiport. Currently I am using Scsiport at the moment as I remember storport bluescreens when i/O becomes heavy. I think a reinstall might be good for it, at least then I can try to use Storport drivers again, who knows they may have updated them since 2008.

    Also I will look into buying locking sata cables, I wasnt aware they even existed to be honest And I will certainly have a thorough read through that thread you linked to.

    Thanks again for the help :)

  3. So, what parts do you have already besides the Q6600?

    Ok you asked for it.... here is the whole story.

    I built a server at the back end of 2008 that has the following:

    Areca ARC-1230 Card with 1GB of ECC Ram.

    2GB of DDR2 Ram

    Intel Q6600

    An Asus Desktop Motherboard (I forget the model but its just a standard desktop board)

    12 x 1TB Drives.

    All was good until I noticed I was getting errors every now and again in the event log, NTFS ID55 errors IIRC. Im running server 2008 and self healing NTFS kicks in and repairs the problem and everything is fine again.

    But it is annoying me like mad, I just want things to run without these errors. I have worked with countless servers and never seen an error as frequent as this, So I am lookinng at replacing the ram + board for something ECC Compatible to see if it stops the errors.

    Thanks

  4. Is ECC Ram not used as often now? :blink:

    What happens with in memory errors? flipped bits and all that? dont they make it down to disk and corrupt the filesystem anymore?

    The same happens as on your regular PC: usually nothing, or very close to that. My question is: and what do you think happens when a CPU does something similar (they all have errata)? Or when a network packet is corrupted? Or when a bit is corrupted on magnetic storage? Or a driver that has a bug screws up some data somehow? (all of these being FAR more common) It's a massive waste of money IMO. Even more so on a home server -- it's not like you're providing services that can't ever go down, or that you are going to countless thousands of dollars every time it does.

    The 2 PCI x16 slots are because I have a raid controller

    Most fancy RAID controllers don't even require a x16 slot. I have some (the cheapo kind admittedly) in x1 slots. I think the most I've seen is a x8, but that's serious overkill. Sure, you can saturate a simple x1 card in RAID as it's limited to 250MB/s (that's still more than acceptable performance in my book for a home server though), but even just a card that fits in a x4 slot has access to 1GB/s of bandwidth -- you're going to need a lot of really fast hard drives to saturate this, or preferably RAID'ing expensive SSDs! A PCI-e x16 2.0 slot has a 8GB/s BW which you probably wouldn't hit, even with 16 high end SSDs in RAID so it doesn't make much sense for them to use that. Then again, your network is nowhere near that fast (good Gigabit ethernet stuff with jumbo frames and everything has about half the BW of a single x1 slot -- that's ultimately how fast you'll be able to get data off from it). Just sit down for a sec and think what you're going to need this for. Personally, I hardly ever need very large files really fast. Most large files I access are movies and the speed required for this is pathetic (around 1MB/s -- a ATA33 drive from the 90's could easily handle it speed-wise)

    Hmmmm, very good reply CoffeeFiend I shall re-consider this entire build.

    Thank you for the help; as usual your knowlegde amazes me :wub:

  5. Indeed, ditch the ECC-RAM idea. I think I know why you brought it up as older times told you to use ECC-RAM in a Server, but that was 10 years ago so say welcome to the modern world we live in now, hell, not even google is using ECC-RAM in their servers ;).

    Now, the 2 PCI-E 16x (electricaly?) sloths is indeed a good question from coffeefiend.

    So, you have a Q6600 you want to re-use? Get a P45 based mobo (GIGABYTE GA-EP45T-USB3P is a great deal at some 130USD) for that with DDR3.

    Is ECC Ram not used as often now? :blink:

    What happens with in memory errors? flipped bits and all that? dont they make it down to disk and corrupt the filesystem anymore?

    The 2 PCI x16 slots are because I have a raid controller to pop in there too and Im thinking If I stick it into the only x16 slot it might not work, at least with 2 i could have a low end vga card and the raid controller in the other slot and it should detect both ok, or maybe Im wrong about this one but I just wanted to make sure it would work.

    and both those boards look great thank you but I really want/need ECC Ram......do you know of any whitepapers on ECC vs non ECC I could refer too? ... im still not comfortable throwing non ECC at it. :)

    Thanks again

  6. Hi Everyone,

    I dont know where to look to narrow my search so if anyone could help that would be fantastic. Basically I am looking for a motherboard with the following qualities:

    support socket Intel 775 (Q6600 to be exact)

    Support DDR2 (must be ECC RAM)

    have 2 PCI x16 slots

    have 2 PCI-express 1x (the really small ones)

    that is all really, if anyone knows of a decent one i would appreciate your help, otherwise I will keep on looking :)

    Thanks

  7. EDIT: Sorry i got this wrong in my orginal Post, now edited:

    I have seen this type of thing before, steps to replicate problem as follows:

    1) Use a fairly large file (ie 15-20gb)

    2) On a 2008 server UNC back to a vista /win 7 machine and copy the file to the server

    3) Bring up taskmgr on vista/win7 and watch the ram usage increase until all available Ram is consumed and the transfer grinds (almost) to a halt.

    Any other way round (UNC'ing from to vista/win7 to server etc) is fine but this paticular way produces this error. I have tried this with various machines and clean installs.

    Has anyone else seen this and does this sound like what you are experiencing agreenbhm?

    Thanks

    EDIT 2:

    From testing i have done in the past i can say that this also happens between 2 Vista clients but NOT between 2 server 2008 servers..

    Anyone got insight into this issue?

  8. None of my family have actually been infected you understand. As i said before and please quote this part IT IS JUST A PRECAUTION, it is my opinion and im sticking by it, of course i use protection, far more than you guys seem to think..... I only gave my point of view on this and got burned :(

  9. I always block all outbound ports as a precaution more than anything else. I wouldn't ever get malware myself but family..... im not so sure about :P lol

    But, then it IS too late already. Because they got infected anyway. ;)

    yeah but no... what if they get some spam generating piece of junk on their system and port 25 is blocked then i win, and pretty soon i would pick up on it from the firewall logs and remove it. Its my preference, and its makes complete sense to me to block all unnecessary outbound ports.

  10. Those Broadcasts will never leave your network, so your safe in that respect, however this is not normal behaviour. I would run a full virus scan, spyware scan and rootkit scan.

    Starting with rootkit revealer since anything potentially malicious should have been picked up by your AV and shouldnt have made it as far as the NIC.

    See what that comes up with and let us know

    Cheers

  11. If you are Using Vista or Windows 7 (which i assume your not from the mention of XP) i wonder if there is a Shim that can do this? (As in intercept the traffic from that program destined for the default G/W and send it to the proxy instead?)

    Alternatively for XP, just some App running a filter driver to redirect traffic would surely be able to do this. Im not 100% sure a shim could do this as its not a typical type of use i'v seen... Anyway there's 2 ideas to get you started let us know what you come up with :)
