Post ipconfig /all for the following machines

Client losing connectivity
Run diagnostics against your Active Directory domain.
If you don't have the support tools installed, install them from your server
install disk.
d:\support\tools\setup.exe
Run dcdiag, netdiag and repadmin in verbose mode.
-> DCDIAG /V /C /D /E /s:yourdcname > c:\dcdiag.log
-> netdiag.exe /v > c:\netdiag.log (On each dc)
-> repadmin.exe /showrepl dc* /verbose /all /intersite > c:\repl.txt
-> dnslint /ad /s "ip address of your dc"
**Note: Using the /E switch in dcdiag will run diagnostics against ALL dc's
in the forest. If you have significant numbers of DC's this test could
generate significant detail and take a long time. You also want to take
into account slow links to dc's will also add to the testing time.
If you download a gui script I wrote it should be simple to set and run
(DCDiag and NetDiag). It also has the option to run individual tests
without having to learn all the switch options. The details will be output
in notepad text files that pop up automagically.
The script is located on my website at
http://www.pbbergs.com/windows/downloads.htm
Just select both dcdiag and netdiag make sure verbose is set. (Leave the
default settings for dcdiag as set when selected)
When complete search for fail, error and warning messages.
