We've just migrated our site and Snitz Forum to a virtual server and were having a number of problems with pages being blocked by something called URLscan (an IIS component I believe).
It turns out that our hosting provider were blocking all HTTP requests that feature a period in the querystring, so pages such as... http://www.myforum.com/admin_login.asp?target=admin_accounts_pending.asp were being blocked. We found other pages were also being blocked but eventually the hosting provider grudgingly agreed to turn off URLscan.
Has anyone else come across this problem and is a URLscan rule that bans periods from querystrings somewhat crude?
