RE: MSDTC Error after applying W2K3 SP2

I haven't received much help over there yet. I was hoping that Florin would
reply with some ideas.

I'm really hoping not to have to burn one of my MSDN support cases on this
one, but time is drawing near when I'm going to have to get those servers
back into the cluster. I'm currently running at 50% in my production
environment.

Could you follow up with him to see if he has any ideas that he might offer?

Much appreciated, Steven.

Thanks for your reply Paul,

I agree with Florin that the Transaction forum maybe the proper one.
Actually, I've originally decided to contact Florin for some ideas on this
issue as he posted something about this in the former thread you mentioned.
So far I haven't any further ideas from the .NET code or configuration
part. If you got any new result from there, welcome to post here also.

Sincerely,

Thanks, Steven.

I reviewed the article and after setting the permissions (they were
already
there under the Advanced settings, but I set them on the main just in
case)
and restarting, the problem persists.

There are no event log entries that relate to this error except the one
logged from ASP.NET in the App log, which provides no additional
information
(I should have mentioned that in the original post).

On Florin Lazar's recommendation, I have posted the problem over in the
Transactions forums, which he says is monitored by the Transactions team
daily. I hope to make more progress there.

Of course, if you have any additional ideas, I'm all ears and appreciate
your help.

Hi Paul,

Regarding on the MSDTC access denied error, I've performed some research
and found that such error is likely due to the default system
registraction
permission has been changed. The service pack maybe installed maybe the
potential cause. The forum thread you referenced mentioned checking the
access control setting(the SACL string ). Here is anther kb article you
can
also have a look which contains some more information about the security
setting and adjustment:

#Systems that have changed the default Access Control List permissions
on
the %windir%\registration directory may experience various problems
after
you install the Microsoft Security Bulletin MS05-051 for COM+ and MS DTC
http://support.microsoft.com/kb/909444

You can also check the system eventlog to see whether there is any
useful
info there. Though I'm not expert on MSDTC /COM+, I can help you check
for
some former or exsting issues. Please feel free to post here if you have
any new finding.

Subject: MSDTC Error after applying W2K3 SP2
Date: Fri, 11 Apr 2008 08:11:02 -0700


Hi -

I have 4 webservers in my webfarm. All Win2k3 web edition. Before
yesterday, none of them were service packed. I have now applied SP2 to
two
of them, and I'm getting a very weird MSDTC error on them now.

The error occurs when I attempt a series of SQL statements wrapped in a
TransactionScope(). It's executing against a different server, so this
is
where it's elevated to a distributed transaction.

The error is:
System.UnauthorizedAccessException: Access is denied. (Exception from
HRESULT: 0x80070005 (E_ACCESSDENIED))

And the stack trace ends here:
System.Transactions.Oletx.IDtcProxyShimFactory.ConnectToProxy(.....

I've checked and double checked all my MSDTC settings, and they're set
properly. I have SP2 running elsewhere on different networks using
MSDTC
and
the settings are identical.

A DTCPing test shows that everything is OK in both directions.

I'm 100% sure it's not my database server because the other two
machines
that aren't SP'd are still executing DT's just fine.

I found this post:
https://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=1974418&SiteID=1

So I ran "sc sdshow mstdc" on the machine where I'm receiving the error
and
got this output:


D:(A;;CCLCSWRPLOCRRC;;;S-1-2-0)(A;;CCLCSWRPWPDTLOCRRC;;;SY)(A;;CCDCLCSWRPWPD

TLOCRSDRCWDWO;;;BA)(A;;CCLCSWLOCRRC;;;AU)(A;;CCLCSWRPWPDTLOCRRC;;;PU)(A;;CCL

CSWRPRC;;;WD)(A;;CCLCSWRPLORC;;;NS)S:(AU;FA;CCDCLCSWRPWPDTLOCRSDRCWDWO;;;WD)

I can't really tell whether that's right or not, though. Can anyone
comment
on that?

I have the same problem on both machines where SP2 has been applied.

Any help would be greatly appreciated.

Thanks,
