Hi!<BR><BR>I made a DLL with some custom controls I wrote, and put it in in. Everything was working fine. Then, I reformatted my HD, and moved Inetpub to a backup drive. When I was done, I reinstalled everything, and moved Inetpub over again. Everything was working ok. Then, I made a tiny trivial change to the code and recompiled. It stopped working!!! Same (practically) code, same exact compiler, and it&#039;s not working! Any idea what the problem could be? Basically, when I go to http://localhost, the process aspnet_wp.exe gets locked in a loop until Windows recycles it, and then IE displaye Error 500. I don&#039;t have a clue what could be wrong. Somebody help!!
