  1. Let's all try to follow rule 7.b, shall we? This thread has been purged of all irrelevant banter - any further abrogation of the forum rules will result in additional moderation. Thank you all for continued adherence to the rules.

  2. You could do this, sure - please note Microsoft recommends in fact that you put the paging file on the SSD because in general it uses small reads (4:1 or more ratio of reads to writes to pagefile.sys on a typical machine) and large sequential writes - precisely what an SSD was designed for. Read for yourself:

    Should the pagefile be placed on SSDs?

    Yes. Most pagefile operations are small random reads or larger sequential writes, both of which are types of operations that SSDs handle well.

    In looking at telemetry data from thousands of traces and focusing on pagefile reads and writes, we find that

    • Pagefile.sys reads outnumber pagefile.sys writes by about 40 to 1,
    • Pagefile.sys read sizes are typically quite small, with 67% less than or equal to 4 KB, and 88% less than 16 KB.
    • Pagefile.sys writes are relatively large, with 62% greater than or equal to 128 KB and 45% being exactly 1 MB in size.

    In fact, given typical pagefile reference patterns and the favorable performance characteristics SSDs have on those patterns, there are few files better than the pagefile to place on an SSD.

  3. I'm not familiar with that device, so someone else who is would have to tell you specifics. However, if you're talking generalities, you'd have to open ports for whatever mail protocols you used, and if the firewall can configure ports based on source IP, you'd base those open ports on the source IP of the end network's public IP addresses, for example. As to specifics, again, I can't give that as I haven't used that router before (I've not heard of it before this, in fact). I did some quick research on it and it looks pretty spartan, so this may not be possible, but you could always ask the vendor (Draytek) if they know how to do such a thing.

  4. I'll make it easy for you:

    Note that newer Windows operating systems like Windows 7 make this easier for you to see - for example, on a Win7 system you can simply run "resmon.exe" and it will show you where the additional RAM was allocated (hint - it's almost always allocated/reserved by the BIOS, and as such Windows never "sees" it as available for use, so it can't use it).

  5. It might be better to configure routing rules on your fw to allow certain traffic to your mail servers from certain IPs (external), so that if the internal VPN link goes down, those clients can still get to and use your mail services using the same name (but hitting public IPs). This is called a split DNS, and I've used this extensively in many environments. If you're a Microsoft shop, using something like ISA or TMG firewalls makes this easier, but it can be done with any product if you know the ports in and out you want to allow, and to which IP address ranges.

  6. Assuming data is still being written into it, save all events to a native pml file, zip or rar it up, and upload it somewhere if possible.

    And that would be one thing I don't know how to do...

    I can force it to write to that folder by deleting the log files that are there and then opening and running the programs that whatever it is creates log files for and they will show up. That part is no problem, I'm lost on the rest of it though...

    That is exactly what you should do then, all while running procmon. Then save, compress, and upload the .pml file (don't even bother to filter this time) and we'll have a look.

  7. This functionality, out of the box, does not exist on Vista or win7. Your only real options without 3rd party software are the sidebar gadgets on a stock install. Otherwise, you would need additional software if it exists.

  8. Is your DNS server configured to use forwarders, or just root hints? If it just uses root hints, what happens if you configure all domains other than internal to use forwarders (and point them at a service like opendns as the forwarding servers)? It's either poisoning (if you're just using hints) or a problem with the upstream servers you're using for forwarding.
