RE: Save while active (SWA) question



fixed

Hey Dave,
Just a quick suggestion to your TCP/IP issue.  There
are probably more elaborate procedures, but just
simply place a program to restart to your TCP/IP on
the job schedular and have it set to kick off about 30
minutes after the SWA would normally bring it back up.
