DHCP randomly is getting unauthorized
Posted on 2012-04-11
We have sites all over the globe and AD/DNS 2008 R2 servers all over the globe too. Today several of our 2003 member servers lost DHCP authorization. At the local 2003 server, the error is that it cannot contact directory services. Yet all tests come back OK. To add to the mystery, DHCP servers elsewhere show that these servers are, in fact, authorized.
I swear it is a network timeout issue but how can I prove this? What tools can I use to dig deep into AD to check this out.
Any help would be great. Thanks.
