Client PCs losing connectivity
Posted on 2014-03-18
After applying server upgrades in early February, I have client PCs that are randomly losing connection to the network/internet. There doesn't appear to be a pattern. The only solution is to log in as a local administrator and change the IP address to something valid. But I'm tired of playing musical IP addresses. Logging into the domain on these PCs results in a totally black screen with only the mouse visible. I need to fully power off the machine and log into the local account.
This problem recently hit a server that is essential for running our business. It holds three server side applications and I'm in real trouble.
Can someone please help?
Most PCs are Windows 7 pro. Main server is SBS 2011 (DNS server) the second server is 2003.
