Windows 2008 R2 Server issue..DNS or CorruptComputer Account
Yesterday my DPM went into a strop and complained it cannot backup our Finance Server that runs SQL2008 on a Hyper-V Host
Intillay I could not even RDP into the server, managed to log in locally and throught he event viewer were DNS warnings, unable to contact servers etc)
Cannot Ping servers (from the finance server) or do nslookups, mapped drives do not work and the time was out on the server, since it cannot see the DC. I could log on the the SQL 2008 Management Studio via Domain login though
No one screamed in finance because the finance drive was up and SQL 2008 was working
First thing I did was to check the cabling on swiches and moved ports (always the simple bits first) and after flushing DNS etc the server managed to do ping by other servers via DNS, nslookup ok.
However, looking at the event log it still can't contact the domain controller, it still won't map to other servers via UNC, and cannot access websites (although it tracerts and nslookups ok for BBC - Homepage for example) and my DPM still cant see it.
From the point of view of the user, the fiannce system is running, they can see the mapped finance drives ok, and I could ping finance machine ok from a PC...so all seems ok there...but would like to sort this out pending bigger issues.
I'm worried that the computer account might be corrupted..and was wondering whether to reset the computer account or disjion the finance server from the domain and rejion again, will this affect the SQL Access?
Thanks as always
