Some Controls aren’t valid
– Please specify an existing server role(s) to uninstall
Easy one – rather than ticking the boxes for roles you wish to uninstall you must clear (un-tick) the boxes.
Accidentally activated an OCS Edge recently, and then renamed it.
Server was marked as un-activated, and when I attempted activation I got the following;
ERROR (0xC3EC794B): Specified role doesn’t match the installed product ID.
Answer was simple – rename the machine back to its prior name, and deactivate the Edge service and uninstall the binaries.
Since Exchange 2007, rollup updates are not necessary show in the EMC/EMS against the server object;
As can be seen above, the servers are all listed as 2010 RTM even though I know I have installed RU4!!
Never mind, this can properly be seen by running the following PowerShell command;
|GCM exsetup.exe | fl|
And checking the “FileVersion”;
Had a bit of a scary moment today – joined the Virtual Centre server to an AD so I could install backup technologies onto it.
All went fine aside from when I opened the vShpere client – all my hosts were marked as “not responding”.
Re-connected the hosts (as it can be seen above) – and the hosts popped back in and then back out again. Hmm not good!
Checked DNS, all right as far as I can see. Checked time sync, all right again.
Rather bricked myself, so off I went uninstalling the Virtual Centre server and reinstalling (using the existing DB) and voila! all is good.
In short, if you do have to join your Virtual Centre to AD, do it before you put Virtual Centre on it or reinstall afterwards!
