I can ping/tracert a PC, but not connect to it in other ways

[Rich]

I have a PC on our corporate domain that is giving us problems with McAfee
(imagine that). However, I'm also unable to connect to its registry, map a
drive from another PC to it, or connect to its event viewer. I've done many
things:

- Run the newest version of CCleaner
- Run updated MBAM (no malicious software was found)
- Updated network card driver/chipset/BIOS
- the firewall is turned off
- Uninstalled iTunes (plus any Apple stuff, including Bonjour)
- Checked for registry entries for "TrueVector"
- looked for programs in Add/Remove programs that I'm not familiar with
- deleted his VPN connection
- Uninstalled McAfee, tested (I still wasn't able to connect to his PC),
then re-installed
- insured "Power management" was turned off (for the Broadcom network card,
he is connected with a network cable)
- under "Advanced" tab on his Network card, insured "Wake Up Capabilities"
is set to None
- His network card is set to Auto - I'm checking with infrastructure to make
sure his port is set to auto

The PC is a Dell Latitude D610 with WinXP SP2

Other thoughts I'm having as I write this email:
- remove and reinstall Network card driver
- use ipconfig to release/renew & flush DNS
- try SysInternals "Process Monitor"
- check for rootkits

Anyone have any thoughts on this matter - thanks . . .
