Performace Monitor and SQL Profiler

Hi,
I was running Performace Monitor and SQL Profiler to keep track of
changes on the server for period of a week. And for some reason this ONE
table keeps getting locked out. The third party vendor suggested that SQL
Profiler creates locks again the users database.
I though the SQL Profiler acquire any locks against user databases, it is
getting information form SQL API directly?
Also the performace counters I read had no affect on the SQL Server...
Is my understanding wrong? Can someone clearify it for me? Thanks!

Microsoft recommends using these kind of tools (SQL Profiler, Performance
Monitor) from another machine. Because they effect performance on the
machine they work. However, in this case they also recommend using a
dedicated connection between those two machines to avoid network traffic
because of using these tools if possible.
So, in your case, yes, they have affect on the SQL Server somehow.

or not. But today I did a trace that logged about 250,000 records on
another database, and that server didn't notice any deadlocks or lock
timeouts. But I did take your advice and this time ran the SQL Monitor on a
different computer. So maybe that had some affect.
So I do suspect me running it on the serer caused locks but might have
caused some slow down. So I think the application is either timing out too
quickly or something else is a miss. Thank-you for your reply.

SQL Profiler will not create database locks unless you are logging to a
database table, which is not usually recommended. In whioch case it is
unlikely that other applications are using that table (or database!)
If you can't log from a separate machine on a dedicated lan, you can use a
server side trace. Make sure that any trace files are not using the same
discs as SQL Server preferrably have fast spindles for it's exclusive use
(although this is rarely possible!)
If you use the SQL Profiler GUI it will use space on the TEMP directory
(even if logging to a file) make sure that this is not the system disc as
running out of space on that, will cause the system to hang.
