Heterogeneous queries and use of OLEDB providers are not supported

Hi all
I am trying to create linked server on 2005 64bit server for 2000 32 bit.
I ran instcat.sql script as microsoft article sugested.
Still, I am having problems.
I can browse db objects using management studio.
But when i try to run sql like:
select count(*) from botserver.master.dbo.sysobjects
I am getting:
Heterogeneous queries and use of OLEDB providers are not supported in fiber
mode.
I can neither run any stored procs.
My linked server is defined as server type: sql server
Any ideas?Why are you running in fiber mode in the first place? Unless you have a
very good reason for turning it on you should turn it back off and solve two
problems.

I have 8 cpu host and content switching is pretty high.
I read that these are indications to use light weight pooling.
If you can please educate me on this point too.
Thank you, Gene.

factors that can be addressed to ease this issue. Things like poorly
optimized queries, lack of proper indexes, poorly configured I/O subsystems,
too little memory, excessive blocking etc. Even other apps running on the
same server can cause excessive context switching. Switching to fiber mode
without addressing the root cause will only cause more problems in most
cases. And fiber mode is usually only really effective on systems with more
than 8 CPU's that are running at or near 100% utilization. I suggest you
concentrate on finding the real bottle necks and think seriously about
turning fiber mode off.

Thank you for your information.
Here I have few questions if you would be interested to answer:
1. Do you think that fiber pooling is the real reason for linked server
problem
2. I have 2 similar servers: 8 cpu, 8gb of memory running 64 bit 2003
advanced server. They both do not run anything but 64 bit 2005 sql server.
One is very busy but cpu is close to 3-5% - plenty of queries but all
optimized and lightweight - mostly inserts and single value indexed selects.
cashe is 99%, no paging. Many hundreds processes access it.
Another server is just idling.
Both have 800 - 5000 contest switching all the time. Which i think is too
high.
Do you think it's normal or typical for given platform?
Thank you, Gene.

linked server issues you have are one of them.
2. 800 - 5000 context switching for an 8 processor server is not that much.
Especially if you have lots happening. That is no where even close to the
range that should be a consideration for fiber mode usage. Turn it off and
you will be much happier.
