Hi everyone, I recently installed Windows 2000 SP4 on our exchange 2000 SP3 server. With SP4, ISM.dll is no longer supported. The .htr extention is not forward to ASP.dll. The problem that I'm having is asp.dll does not understand the our .htr files. So when using OWA, the change password functionality no longer works. I can go into IIS and change it back to ism.dll and it works great, but just displays "page not found" when .htr files are configured to use ASP.dll. This is exactly the problem I'm having: http://support.microsoft.com/default.aspx?scid=kb;en- us;331834 According to the article, ASP.dll should handle the .htr request. It does not. I've not confirmed this problem on two of our exchange servers and 3 other companies exchange servers. Any help on how to get asp.dll working correctly? _________________________________________ Dinh Xuan Ngoc Hue Software Park Tel : 84 54 823791 ext 11 Mobil : 84 913 465 189 Email : dxngoc@xxxxxxxxxxxx _________________________________________
