Exchange 2003 to 2010 PreChecks
I am in the process of upgrading our Exchange 2003 to Exchange 2010. As part of that process I am running "dcdiag /test:dns" etc.
I have 2 DC and whichever machine I run the diagnostic from the other machine will fail at the 'Basic' test stage.
Initially the problem was flagged up as 'WMI' not implemented but after resolving that I have a 'WMI Successfully Installed' message displayed.
However, I now get the error message 'Win32: RPC Server not Available'.
Using Computer Management I can successfully connect to a remote server but cannot get data. If I use a workstation to remotely connect I can only get success from another workstation not the servers. From the servers I cannot get any success.
I have been trawling the net all day but seem to be no closer to identifying the problem.
Have any of you any new ideas?
Thanks and Regards
