JCE

I reinstalled MCE and everything works again. I guess it was Windows that was somehow F'ed up. Thanks for all who tried to help.

Creating a new account and share didn't work. Everything appears to be as you quoted it. I'm really getting irritated that I am going to have to reinstall.

One machine has the .NET passport password stored (and nothing else) and the other has 1 password stored not related to the server machine. The server machine has no stored passwords at all...is that a problem?

I pinged them right after I switched to the last of my routers and they all pinged perfect to and from the computer with the problems. When the other networked computers click on the Workgroup icon in the Windows Network tree they can see the problem machine but get this message when they click on the machine: I'm truely at a loss as to what is causing the problem. At least I'm not the only one having this issue--but it seems there isn't an actual fix since the solution from the MS Knowledgebase is completely rubbish.

Correct. That's good info to know. And my Guest account is enabled. I'll try this and see if it works. I'll edit my post afterwards. I'm not running any sort of web server or anything hardcore enough to need Server 2003. I just prefer to run MCE, and considering I use my server to play games and the like I need better multi-media support. I've had bad luck with Server 2003 and driver support in the past. I ran Server 2003 for almost 2 years and loved it--now I don't feel I need it. *edit* Well the above didn't work. Any other ideas?

The only thing I did was disable the Guest account, then turn it back on again. Could my TCPIP.SYS file be corrupted? And if so how do I restore it? I tried copying it in the dllcache and drivers folder--but the previous file put itself back upon restart.

Here's an interesting problem. About a month ago everything was working peachy-keen on our network, and within the last 2 weeks out of the blue the other 4 Windows machines on our network can see my computer but can't connect to it. Here's our network setup: 5 computers (1 notebook and 3 desktops and 1 server workstation) all using XP MCE2005. (6 if you count our Apple G4) 3 computers are hardwired to the router. 2 computers are using wireless. 1 computer is a Dell Precision server (my computer--the one having the problems). My machine (Dual P4 XEON server) is our main media server for the entire network, so you can imagine why I need the rest of the network to be able to connect to my machine and transfer files back and forth as well as stream audio/video. My machine can not only see everyone on the network but can send and copy files to/from them. But when the other 4 machines try to stream or copy files FROM my machine to THEIR machines they get this error. Problem is they have the correct permissions and the services are how they should be. I haven't changed anything but my computer description in the last 3 months to cause the problem. I'm sure I either missed something or Windows is taking a crap on me. Things I've tried to remedy the issue: Recheck services to ensure nothing's disabled/started. Good. Recheck sharing permissions. Settings are as they should be. Good. Run anti-virus and anti-spy/ad ware programs to ensure there isn't anything malicious at work. Good. Reinstall network card drivers--in my case its integrated and Windows XP automatically detects it. Good. Try another router. Infact I tried 3, all produce the same issue. Its not a router issue. Good. Try another network card. I tried 2, one PCI wired and 1 USB WiFi. Its not my network card. Good. I'm at a total loss as to what the problem is much less how to fix it short of a reinstall of MCE. I would prefer NOT to have to reinstall--but if that is my ONLY option I would do it. Does anyone have even a remote CLUE what my problem could be? I've run out of ideas and I need a fresh brain.
