When I run the Server Managment Application it opens up fine.
If I then try to run any of the wizards it opens up the wizard I request then when I select Next it closes down.
I am awaire that this was an issue with SP 1 & 2 and the easy way would be uninstall SP2 and then setup Remote Access then reinstall SP2 but thats not an answer I want to do.
When I was looking at adding user cal's a couple of days ago it was crashing as per above. I went into somthing and ticked a box that allowed me to carry on. I cant remember what I did though.
