Well, Outlook connects to the back-end directly so the front-end/back-end configuration has nothing to do with it.
You may want to do a traceroute from the client to the server as well as ping -t and see how the connectivity is doing. Also you may want to change the RPC Provider order in the registry on the client PCs. Put whatever protocol you are using on your network in the first place. -----Original Message----- From: Stephens, Tara [mailto:[EMAIL PROTECTED]] Sent: Wednesday, May 15, 2002 8:36 AM To: Exchange Discussions Subject: Authentication issues We have an E2K SP1 active/passive cluster running on W2K SP2 with approximately 700 users in a single store. We have a front-end/back-end scenario. Clients run W95/98/W2K and Outlook 98/2000/2002. Gradually over the last couple of weeks, we have been getting more and more users complaining that they can't get into Outlook the first time they open it. They get "network problems are preventing connection with exchange...". If they try again, they can usually get in. It doesn't seem to matter if the user is on the same 100mb switch as the mailserver or on a t1 wan connection. No changes have been made to the mail servers - front or back end. There is nothing in the event log. The server utilization looks normal. We aren't having any other authentication or name resolution issues with other applications. We've changed our firewall within the last month to ISA from Raptor and a server for instant messaging. These are the only changes. Any ideas what could be causing the error? Is there something else I can monitor?
