Hi,

Here's my case. I have a PC workstation running Windows XP Pro SP2 (all recent updates installed)

On it I run the following network/web software:

- Serv-U FTP 6.02 with 3 users (one admin, myself, and 2 clients) NO anonymous accounts
- e-mule 0.46a
- Remote Anything 5.11.22 (personalized slave.exe with hard-to-guess password)

As security software I run ZoneAlarm Security Suite 5.5.094.
As spyware & antivirus I run McAfee Antispyware and McAfee Viruscan (both having last signatures databases) and the system was fully scanned.

Now the hardware part: I use a Mercury KT133a FSX mainboard, Athlon Thunderbird 1.1 GHz, 256 MB RAM, 40 GB WD HDD, Nvidia TNT2 Ultra video. I checked the system using BurnInTest Pro 4.0, stressing it for 24 hours, at 100% CPU, temperature never went over 55C. All went well.

BUT, here's the problem: once in a while (daily or every 5 days the most) my server FREEZES. No mouse, no keyboard, nothing works. Only the reset button can change anything.

I tested all I am aware of but I can't figure out what is happening... Because it's terribly frustrating... Is it a security problem I'm dealing with? And if yes, what can I do about?

Please help me,
Thanks
