ADO.NET Timeout Exception - I Have Tried Everything

Hello!
I am looking for someone who has solved this multi-million people's
problem. EVERYONE seems to ahve this problem.

Im a creating a data set and populating it with a call to a store proc.

Its a complex stored proc with the end result as an insert to a temp
table. Then I do a select from the temp table - in the store proc.


I get the following sqlException error on the following line:
DataAdapterName.Fill(DataSetName, "TableName")


The error is:
Timeout expired. The timeout period elapsed prior to completion of the
operation or the server is not responding.


My connectiong string looks like this:
<add key="cnITDevWinUser" value="Data Source=server; Integrated
Security=SSPI; Initial Catalog=dbname; pooling=false;connection
reset=false;connection lifetime=5;min pool size=1;max pool
size=10;connection timeout=120" />


I have admin rights on that db.


I have set my command.timeout to 500.


If i run this same code in a windows application, it works fine.
If I use a DataReader with the same storeProc, it works fine.
If I run this same code on a simple selec (hello world), it also works
fine.


If I run this store proc in QueryAnalyzer it works fine and is done
within 6 seconds.
If I run this on a different machine it produces the same result.


I am using SQL2000 with vb.net in VS2003.


I have looked everywhere for the answer. I can't find it anywhere.
PLEASE SOMEONE HELP.

Stas K.(a.k.a Sorcerdon)
