http://support.microsoft.com/support/kb/articles/Q147/7/75.asp http://support.microsoft.com/support/kb/articles/Q147/7/72.asp -----Original Message----- From: Paul Owen [mailto:[EMAIL PROTECTED]] Sent: Wednesday, October 03, 2001 11:01 AM To: MS-Exchange Admin Issues Subject: Site connectors between NT & 2000 server We have two Exchange 5.5 SP3 servers in different domains, one on NT4 and one on 2000 Server (don't ask why, way too complicated & political). Users homed on the 2000 server now need access to calendars on the NT server. The 2000 server is NOT a domain controller. The two domains have a 100Meg LAN link. I can't get Exch5.5 on the 2000 server to communicate via a site connector with Exch5.5 on the NT server (still with me?), I get a DS_E_COMMUNICATIONS_PROBLEM error. Technet article Q150880 seems the only article remotely relevent, and says "If the Exchange Server computer is only a member server of the domain and not a PDC or BDC, remote administration will not work. The Exchange Server must be either a BDC or a PDC." Anyone know if it's possible to get around this, or am I missing something? I don't really want to have to remove 2000 for NT, nor do I want to install Active Directory.
