I currently manage 4 SBS 2003 installations. We ran into the issue at one installation of Exchange store.exe taking a large amount of memory and we recieved the warning. I've doen the research and have plans to deal with that. In my investigation, however, I came across the task "sqlserver.exe". I have never setup a SQL server on the system. More strange yet is that i noticed that there was not one, but TWO instances of sqlservr.exe running on the server. In case it matters I am remotely connected at this point.
To expand my search, i remoted to my other 3 installations. One of the other three had the same situation. So I have two installations that have two instances running, and I have the other two installations with only one instance running in the task manager.
The two sites that have two instances are both running exchange 2003, serving as their mail servers (internal and external). Both are running Trend Micro Server/Client/Messaging Suite for virus protection.
Of the two other sites. They are both running exchange as their mail servers (internal and external). One is protected by Symantec and the other the same Trend Micro product.
I can't seem to put things together to come up with a reason why some are doing it and others aren't. The main reason I'm asking is because these are taking large amounts of memory in proportion to the number of users they service.
Any advice? Thanks
