Remote Procedure Call failed and denial of port on Local Host by I

Hi everyone,

Have an SBS 2003 R2 box with ISA 2004 installed on it.

About 2 weeks ago I started having problems publishing folders to active
directory, joining computers to the domain and all sorts of other problems
that seemed to be related to Active directory.

Here are the error events in the logs:

Application Events

Source: Userenv
Category: None
Event ID: 1053

Windows cannot determine the user or computer name. (The remote
procedure
call failed and did not execute.). Group Policy processing aborted.


Directory Services Error
Source: NTDS General
Category: Global Catalog
Event ID: 1126

Active Directory was unable to establish a connection with the global
catalog.

Additional Data
Error value:
1355 The specified domain either does not exist or could not be
contacted.
Internal ID:
3200d11



Directory Services Warning

Source: NTDS General
Category: Global Catalog
Event ID: 1655

Active directory attempted to communicate with the following
global catalog and the attempts were unsuccessful.

Global catalog:
\\server.domain.local

The operation in progress might be unable to continue. Active
Directory will use the domain controller locator to find an
available global catalog server.

Additional Data
Error value:
1727 The remote procedure call failed and did not execute

Now, there is also a mysterious denial in the ISA log entries whenever I
attempt to publish these folders to AD. It denies a connection from the SBS
Internal Lan IP (Source: local host) to port 1025 on the SBS Internal Lan IP
(Destination: Local Host) and it uses the default rule as the justification
for this denial.

I've tried to create a local host to local host all allow rule and nothing.
I've also tried to specifically allow 1025 tcp traffic from local host to
local host and nothing.

What gives? Does anyone have any clue whats going on? Is this really simple
and I'm just overlooking it?
