More findings.
1) With the ASP file listed at the end of this post, If
1.1) I load the ASP on Server A, where Server A
1.1.1) contains the target DB as stated in connection string
1.1.2) running IIS6.0 on a Windows 2003 Server
1.1.3) Running SQL Server 2000 SP3a
Then, The ASP run successfully displaying "db openend" and "record updated"
1.2) If I load the ASP on a Windows XP Professional SP1 machine B
1.2.1) with the ASP containign the same target DB as stated in connection
string
1.2.1) Running windows XP Pro SP1, IIS5.1 on the same domain as the Windows
2003 server A
Then I get the following error:
ERROR-2147168246
New transaction cannot enlist in the specified transaction coordinator.
I have played around with the following (following the articles/newsgroup
posting you suggested)
1) MSDTC is definitely started
2) Machine pings OK
3) SQL Client is set to use TCP/IP only with Enabled shared memory unticked
4) Transaction timeout set to 80 seconds (although the error is returned
straight away!)
5) On Component services:
5.1) Default Properties Tab:
5.1.1) Ticked Enabled DCOM on this computer
5.1.2) Ticked enable COM Internet Services on this computer
5.1.2) Default Authentication level set to: Connect
5.1.3) Default Impersonation tried: Tried all 4 settings ( all results in
same error)
5.2) DCOM Security Tab
5.2.1) Ensure IWAM_MachineName and IUSR_MachineName has launch premission
5.3) MSDTC Tab
5.3.1) Ticked Network DTC Access, Network Administration, Network
Transacitons and XA Transaction
5.3.2) DTC Logon Account:
5.3.2.1) Set to LocalSystem
5.3.2.1) If I try to set to a Domain account that belongs to the Admin group
on both the WinXP Pro and windows 2003 server server, I get the following
logged:
Event Type: Error
Event Source: MSDTC Client
Event Category: MSDTC User Interface
Event ID: 4429
Date: 15/11/2004
Time: 09:37:56
User: N/A
Computer: WindXPPro
Description:
Failed to set the security attributes on the MS DTC service. Internal

6) Note the MSDTC Trace files at %SYSTEMROOT%\system32\MsDtc\Trace are
pretty binary and meaningless to me!
7) Note I only get a problem with the ASP file if Transaction attribute is
set to Required or ReqruiesNews!
