dll hangs

[Von Shean]

I have a dll in .net that is used by another dll. The second dll is used in
the web and the first one acts as a middle layer. The dll contains
non-transactional and transactional classes. I have registered the dll in
com+ services using regsvcs. Non-transactional works fine. But the calls to
transactional classes hang when called by the second dll.
I execute a SqlHelper.ExecuteReader.
No call to the database is made.
Looking at the eventlog i get different entries. The most common one was


Server stack trace:
