I have RPC over HTTPS published through ISA 2004. It has been there up and running for three years now. Users are added on occaisional basis and there is no problem at all.
A couple of days ago, I started witnesseing something weird. And no other user has reported a similar problem to me.
When I start Outlook in RPC over HTTPS mode, I am asked to provide my password. It has always been the case and that is ok. However, now, that password box would repear every, say, five minutes and ask for my password. Sometimes, the dialogue box is titled "Connect to <server name>" and other times it is titled "Connect to <FQDN of exchange server>" The weird thing is that no matter how many times I key in the password, it keeps popping up again and again.
I am not aware of anything that I have done in Exchange server that might have caused this annoying issue to arise.
Any input is highly appreciated.
