After a recent migration of mail to Exchange2007, we’ve just started getting users logging tickets where a security window pops up saying “The name of the security certificate is invalid or does not match the name of the site”. This can happen even when the client is not at their desk. It took a few seconds to work out what was causing it – the clue was that the window had an icon in the taskbar for outlook. Searching in Google found Microsoft’s KB article 940726 with the resolution to the fix which involves changing various internal url attributes.
The instructions are fairly straightforward but I wanted to see what the values were set to before making the change. As I’m not very familiar with powershell it took me a while to work out what I needed.
For the command

Set-ClientAccessServer -Identity Servername -AutodiscoverServiceInternalUri https://name.contoso.com/autodiscover/autodiscover.xml

you want to run the command

Get-ClientAccessServer -Identity Servername | fl
The pipe fl provides all the values in a list – if you don’t include this part of the code you will end up with one line containing the name of the server – a value that you hopefully know already!
I really need to get cracking on my powershell skills – I still prefer good old fashioned dos batch programming but now that we’ve started to roll out powershell across all machines, powershell skills will be in demand more and more.
