I have a stored procedure it works great on SQL Server 2000 Developer editon and the query performance is close to 1 min and then we deploy the same stored procedures on
Enterprise and Standard Edition (SQL2000) it does not work, it just keeps on running.

Any idea whats happening when we move the stored procedure to Enterprise and Standard, why it is not working?

Could you please share the stored procedure details? What it does? The input you provide to the SP in both editions are same?

By debugging the SP you can findout where it goes wrong. http://www.codeproject.com/KB/database/SQLDebuggingVSNET.aspx

Everything is exactly the same. The query is very big, i may not be able to send but this is what it does.It creates few temporary table (Clustered Index), queries the records close to 25 million.
It is all select,insert into temp tables which have a clustered index on it.

Can you suggest some pointers?

I hope the SP you run in the Standard Edition could be cached and it seems like it takes less time. But in Enterprise edition you run first time. As there is no cache this time, it takes long time I guess.

Most probably it would be related to Query fine tuning. Instead of temporary table you could consider using Views/Table Variables. If you use order by then remove and see what happens.

Enterprise and Standard Edition (SQL2000) it does not work, it just keeps on running.

Wait until you get an error message or it finishes (if so re-run to see if  speeds up)..also check the enterprise server settings...about memory allocated

so you tested against a 25 million row table in the developer edition?

you have confirmed that all

 indexes are the same in the different environments
 triggers are the same and present
 indexed views/partitioned views

 what about the placement and size of tempdb/ physical server ram...

 are any other processes running on the server  which where not running to the same frequency/spec in the developer environment

are statistics uptodate in the "production" environments

please post the procedure or provide more detail general information...
e.g. how are the temp tables populated?
what loops/cursors are used
how is the stored procedure invoked?
how many users does the environment support?
can/is the procedure executed concurrently by multiple users...

what filters does the procedure apply to the tables it processes...

Because your data, server or some other factor is different.  This has nothing to do with the edition, whatsoever

I concur with previous comments.  What tells you that the deployment failure is due to edition ?

From the tenure of your question, I'd say that there is something that prevents your procedure from running in a non-FIFO environment (Production environment are not).  Look at blocking or deadlocking.  Please post the showplan of the procedure and check whether there are any indexes missing.
