Not enough memory to load this application

We are currently having the error on MANY machines at work, and are unable
to fix the problem.

We also have to schedule a task to run every hour to fix time issues. The
time is constantly getting way behind, several
hours.

So we are having to constantly reboot out machines, which causes delays in
getting files processed, etc.

We are running Windows 98 SE, F-secure, and batch loops on start up. the
batch loops are constantly looping
checking directories for files, and processing them.

After awhile, you cannot run any DOS applications without getting the low
memory error, and the time gets behind.

Any ideas? I am at wits end on this issue.......

Thanks in advance.
