Problem with deadocks

Hi list, iam very new to SQL. i have a developer that is making a very
complex query over a SQL2000 + SP3 database, with a lots of union queries.
He recieves this error:
Transaction (Process ID 97) was deadlocked on lock | communication buffer
resources with another process and has been chosen as the deadlock victim.
Rerun the transaction.
I dont know how to proceed with this, how can try to discover the problem?
Could be a resources problem?
Thanks for the advices...Aswers in microsoft.public.sqlserver.server
