RE: [ActiveDir] Exchange Authentication and WinXP Workstations

[Joe Pochedley]

Edwin,   You say that "other clients" can connect to your Exchange Server from the outside network?  Do you have a firewall in place between your inside and outside network?  How are you making your Exchange server available to the public network (Port publishing on the firewall for RPC, RPC over HTTP, or VPN maybe)?   Is this XP user using a different ISP than the others who are working correctly?  Many ISP's block RPC, if that's the method you're using...  Home HSI connection behind a NAT router maybe?   Heck you haven't even told us if you can successfully ping the Exchange server from this XP machine on the "public network"  I guess we just don't have enough info to really understand your problem...   Joe Pochedley A computer terminal is not some clunky old television with a typewriter in front of it.

All machines?  That makes a big difference for the solution that needs to be used.   What gets logged on the domain controller when you attempt this (assuming you have audit logging enabled)?   What happens on the wire during the attempts?  Network trace?   From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Edwin Sent: Thursday, September 09, 2004 8:57 AM To: [EMAIL PROTECTED] Subject: [ActiveDir] Exchange Authentication and WinXP Workstations Recently I was informed that users attempting to connect to our Exchange server when using WinXP are experiencing troubles.  The error is that it cannot connect to the exchange server.   I do not see any errors on the client XP machine or on the Exchange server itself.   For some reason I am able to open the MAIL application within the control panel and successfully connect and authenticate to the Exchange server.  But when you do a "Check Name" the error is returned that it could not connect.   I found an article on Microsoft's site but it seems a bit extreme.   http://support.microsoft.com/default.aspx?scid=kb;EN-US;255843   Has anyone else encountered this?  Was there an alternate solution?   Thank you all for your replies.   Edwin
