RE: VMWARE on 2003 Server

Tech Tip: Click here to run a free scan for Windows Errors and optimize PC performance

Thanks for the info, I think I understand what your saying about the
networking, I'll give that a try if it acts up again. I just got a message
back from the net admin, they broke the team on the second server and they
seem to be working well together now. I broke the team on the first server
because it was usually the one that quit working. now that both are not
using a team, both servers are up and working ok so far. I can't explain it,
but that may have been the issue.

Thanks for all your help, you were very helpful!

Thanks
