Please correct me if I am wrong - but setting AWE won't have any affect on this system because it only has 4GB of memory. To be able to use AWE, you would need more than 4GB of memory - and then the memory above the 4GB could be accessed.

What I believe is needed here is the /3GB switch enabled.

So, would something like -g700 be appropriate as a startup parameter to help the Linked Server memory issue ??

Maybe. But it's a temporary mitigation. If you have stuff fragmenting MemToLeave, increasing the size will delay the problems, not prevent them.

Also, that means that, without AWE or 3GB, you now have 1.3 GB for SQL's buffer pool and other caches, not 1.7.

I did enable AWE last week, set max memory to 3G, then restarted SQL.

If you're going to add -g700, I would suggest dropping that to 2.5GB. Otherwise, 3GB for SQL buffer pool, 700MB for the MemToLeave, doesn't leave much for the OS.

I notice now, a week later, Task Manager only shows SQLSERVR.EXE using 105 meg. I was expecting it to be much higher. Yet I still get errors trying to update 1 record through a linked server.

Task manager lies. Don't use task manager to check SQL Server's memory usage, it will often show far too low (limitation in Task Manager). Use performance monitor and the Total Server Memory counter.

Not sure if I'm reading it correctly

"Total Server Memory (kb)" shows a flatline at "100" in the graph. The "last", "avg", "min" and "max" boxes all show 3.2 G.
That looks better.
