Problems Executing A SELECT Inside A TRAN Against Other Computer

Hi
I have a problem executing a SELECT inside a TRAN against other computer

For example:
IN THE SQL Query Analizer of the COMPUTER2
1) this runs OK
BEGIN TRAN
SELECT * FROM COMPUTER2.DATABASE.DBO.TABLE
COMMIT TRAN
2) this runs OK
SELECT * FROM COMPUTER2.DATABASE.DBO.TABLE
3) this runs OK
SELECT * FROM COMPUTER1.DATABASE.DBO.TABLE
4) this runs bad
BEGIN TRAN
SELECT * FROM COMPUTER1.DATABASE.DBO.TABLE
COMMIT TRAN

The problem is that TABLE locks and it does not finish.

I've been looking for similar ERRORS in Microsoft Support but I found nothing
I've uninstall and install de SQL server 2000 SP4 and the problems continues the same


Please, someone could help me, thanks
