Hello! [We have Exchange 2000 Enterprise in mixed environment] We have problems with our OWA placed in DMZ (which is a front-end server) with contacting GC and DC's. We've opened the ports specified in KB 280132. We also made the registry hack on our DC's in the same article. But still we get intermittent errors. Seems like that RPC traffic don't get through. I've read that we could do a registry hack on the actual front-end server as well, to control RPC traffic. Where can I find information about this? Thanks in advance! /Björn -------------------------------------------------------------- This e-mail and attachments may contain confidential, proprietary or legallyprivileged information.
