Linked Table Slow

I am connecting to SQL through OBDC from MSAccess.  I have approx. 50 machines that will be using the SQL. There are currently about 15 machines on SQL. about 25% of them run very fast. the other 75% run very slow.  All the odbc settings are the same, all the SQL drivers are the same. It seems to be computer oriented.  The same machines run fast no matter what scenario.  What network protocol should I be running and would this make a difference.

What you might be running into is a network protocol problem.  I have seen similiar problems where the client was running IPX, TCP/IP and NetBeui.  Unless you have specific needs (i.e. connecting to a Novell server) then I won't run IPX.  NetBeui should do the job for you just fine.  You can also run TCP/IP at the same if you need it (for Internet connectivity and the like).  You will also need to make sure that your NT server is running the NetBeui protocol.

Also, some performance differences can be measured by the hardware.  For example, a pc with a Pentium II 400 is naturally going to run things faster than a 486.  Another difference might be the amount of memory each workstation has.  If some of the workstations have less than 32 meg memory, you could be running into a situation where the operating system is spending time swapping in and out from virtual memory.

I hope this helps.
