If anyone has that answer I would love to know. I know for sure that we
rolled out our original XP image missing one of the keys. A couple of
months later a few machines experienced the problem. I still run into a
machine every couple of weeks that has this problem for no apparent
reason. There is something user specific even though the registy entries
are machine specific.
I use the VBScript below to resolve this issue when people run into it.
------------------start of script--------------------
' This script will put in place the client protocol registry entries
' needed for Outlook XP. Not have these can cause a prompt for
credentials
' when opening Outlook.
Option Explicit
' Declare all variables for the script
Dim strKeyPath, refRegistry, strComputer
strComputer = InputBox("Enter computer name to fix")
' Sets registry path where values will be written
strKeyPath = "SOFTWARE\Microsoft\Rpc\ClientProtocols"
' Set a constant that will reference HKEY_LOCAL_MACHINE key
Const HKLM = &H80000002
' Gain access to the remote registry
Set refRegistry = GetObject("winMgmts:\\" & strComputer & "\" &
"root\default:StdRegProv")
' Write the necessary values to the registry
refRegistry.SetStringValue HKLM,strKeyPath,"ncacn_np","rpcrt4.dll"
refRegistry.SetStringValue HKLM,strKeyPath,"ncacn_ip_tcp","rpcrt4.dll"
refRegistry.SetStringValue HKLM,strKeyPath,"ncadg_ip_udp","rpcrt4.dll"
refRegistry.SetStringValue HKLM,strKeyPath,"ncacn_nb_tcp","rpcrt4.dll"
refRegistry.SetStringValue HKLM,strKeyPath,"ncacn_http","rpcrt4.dll"
MsgBox "Done"

Kudos to Dave. Thanks
Yup this was the issue. I took a look at all the clients experiencing
the issue, and sure enough they were missing the entries in the
registry. Funny thing is that I had the similar issue when we migrated
to Exchange 2003 from 5.5.
Some of my clients had the same issue, and I corrected by adding the
registry entry. These are completely new clients that experienced this
issue. All I did was reboot the exchange server? Any idea why the
outlook clients decided now not to function?

Hey Guys,
This is a weird one. I rebooted my exchange 2003 server last night.
Everything came up ok, and access to e-mail. This morning I had roughly
20 users that could logon to the domain, but when launching outlook
would get the exchange credential login popup? If you entered the
user's login info it would come back saying the user name and password
were incorrect. Rebooting the PC seems to help for some reason
temporarily, but the issue would come back again after a while? Running
Windows 2000 server & AD. Most clients running Outlook XP. Any
thoughts?
