I have 3 IIS intranet sites setup, 2 on Win2k and one on Win NT 4.0. The one on Win NT 4.0 will maintain a sessionid for a browser, but the two Win2k machines won't maintain session state. Every time I refresh a page to display the session id, the session id is incremented. I've tried matching up the options within the IIS on WinNT with that of Win2k, but nothing has fixed the problem. Any help would be much appreciated.
