Re: RPC Server Is Unavailable on 2003 TS but not on 2000 TS

Hi Vera,

Info as requested :-

When this problem occurs, what is the exact error message that the users receive, if any?
In a Dialog box
Logon Message
The system cannot log you on due to the following error:
The RPC sever is unavailable

Please try again or consult your system administrator.


Do they get this before or after typing in their username and passowrd?
This happens immediately after entering the password

Do they get to the logon window in the first place?
yes

And can you logon to the physical console of the server when the problem occurs?
Yes

We even tried restarting the Netlogon service (suggested in another post) to
see if that will allow users to logon again, but with no success.

OK, I understand.
No, hotfix 883670 was not included in SP1, but released very
shortly after it. So it's perfectly possible that you already have
a newer version of the file, through another hotfix or Windows
Update.
In that case, there's no need to get the hotfix.

Hi Vera,

Thank you or your reply.

In my haste to post, I forgot to mention that I have already
tried quite a number of things based on previous posts on
Technet as well as posts found doing a Google search, obviously
with no success yet other than to reduce the frequency of this
error occurring (but not erradicate it - this problem has been
ongoing for a few months).

In reponse to your suggestions :-

1) I have rechecked the network settings a number of times - and
have also run a number of diagnostics based on previous posts
(NETDIAG, NETDOM, etc.) and all tests always comes back as
passed when the problem is not occurring. The gigabit network
switch and connecting network cables are new (replaced when
problems first showed up) and have also changed network cards to
be thorough. As the old W2K TS isn't showing any errors, I still
think the probem lies with the 2003 TS.

2) I checked the 883670 per your suggestion - however, I think
that is already included in SP1 as the version currently on the
server is a lot newer and has a much higher version number than
the one mentioned in 883670.

Any further suggestion will be most appreciated.

Kelvin

Hi,

This is an ongoing problem since putting in the 2003 TS
(problem exists from the very start). This problem does not
occur with the existing 2000 TS.

Environment :
SBS 2003 Premium (Dual Xeon 3.2Ghz, 4 GB RAM, RAID 1 OS, RAID
5 Data with ample free disk space)
Serving approx. 35 users
Exchange IS is at about 10 - 14GB usually
There are 2 major SQL applications running all the time
TrendMicro CSM for SMB is their AV solution running on the
SBS server

Old W2K TS : Windows 2000 Server SP4 (Dual AMD Athlon MP, 2GB
RAM, RAID 1)

New 2003 TS : Server 2003 R2 Std 32bit SP1 with all current
Windows Updates loaded (2 x Dual Core Xeon 3.4Ghz, 4GB RAM,
RAID 10)


The existing W2K Terminal Server works fine with all their
applications loaded and they only put in the new 2003 TS
because the W2K TS is getting too slow to run their
applications for the number of users in the office. The same
line of business applications are loaded on the new 2003 TS.

The problem only shows up on the new 2003 TS and only ever
appears during logon. If there are already users logged on
when this problem occurs, the users already logged on appears
to be unaffected and can carry on without knowing there was a
problem. However, the users attempting to log on when this
occurs generally must wait some number of minutes before
attempting to log on again and very often succeed in logging
on after waiting a while. And it can be any user and not
particular to any one or group of users (including the
Administrator).

System & Application logs shows a variety of errors (when the
problem occurs at different times) :-
Eg. Event IDs : 5719, 1053, 1219

They may go days without seeing the problem and they may
suddenly have it occurring every day or every other day or
sometimes several times a day. Rebooting the terminal server
lets users login again immediately (until the problem
reoccurs) or they could just sit and wait several minutes and
the system will then let them login. Note that whenever this
problem occurs, they could still log in to a session on the
old W2K TS.

They have tested logging the entire office in to the 2003 TS
(without starting any applications after logging in) and that
did not produce any errors. As it is intermittent mostly, we
cannot "cause" it to happen to try and narrow down what it is
that is causing it.

Please help ! The client is threatening to return the entire
server, OS, Software and all unless this problem is resolved
!
