Every time I see "PMTU discovery" I think of "The Crying Game."

Try installing the RPC fix and maybe enable PMTU discovery.

The ISA server / domain controller has been up for 2 years,
upgraded to SP1 over Christmas holidays.  This server with the RPC
problems was also setup over the holidays, joined a workgroup first
during install, performed Windows Updates, updated to Windows 2k3 SP1,
then joined the domain.  Didn't notice any RPC problems at all until a
program we installed required MAPI and noticed strange Exchange behavior
when connecting.  Installed the KB897716 late yesterday afternoon, fixed
Outlook/Exchange problem, but created a TS RPC Error on logon.

SCW is not installed on either machine.  Does that help you more
Amy et al, as it sounds like you thought my server having problems was
an SBS from your questions.

Now the truth is coming out. RPC and LDAP can be related problems. Fix RPC and your LDAP problem will probably also go away. Did you use the SBS install routine when setting up this server? Did you run the connect to the Internet wizard when prompted and choose "enable firewall" therein? Or did skip the wizards and configure it from scratch?

To further clarify, I was having RPC errors on this same
machine, so I went ahead and installed 897716 as the error matches the
error we were

seeing in Exchange, so we installed. Now we've been getting "The

system cannot log you on due to the following error: The RPC
server is unavailable" when trying to RDP in as any user (other than
Domain Admin), and when I run ISA logging, I noticed LDAP is being
refused (also with Kerberos-Sec like I said yesterday, but that was
being blocked before).

Is there any reason why LDAP would be refused now between this
machine and my SBS with ISA?  This Apps server is part of the Internal
network range.

WHOA.



Are you saying this is ISA on SBS?



That's quite different and a "oh by the way, how was the play
Mrs. Lincoln" moment :)
