"Security check" window pops-up and need for remote software.

"Security check" window pops-up on my remote session; this
occurs when I'm trying to transfer a file during my remote
Closeup session from with a DOS window under Windows XP.
It seems to prevent me from tranfering files in the DOS
windows during my remote session.

This never occurred when I ran the CloseUp remote software
(i.e. older DOS version of Closeup) in a DOS window under
the Windows 98 system.

Therefore, my questions are these:
1) How can I COMPLETELY disable the security checks on
file-transfers that I initiate under the Windows XP
system? Because if I decide to initiate a file-transfer
(whether in my remote DOS connection or any other way), I
don't want the Windows XP security check to second-guess
my decision (i.e., if I initiated the file-transfer from
my end of a remote connection -- either in CloseUP remote
software or on the Internet -- however, the internet has
not been a problem, only the old CloseUp software has had
the problem).

2) What is a good remote software that will allow me my
Windows XP system to communicate with a DOS computer that
doesn't have a windows enviroment? Windows 98 ran my
older DOS CloseUp software fine for this; but my newer
Windows XP system is not working very good with the older
CloseUp DOS software for my remote connection to a DOS PC.

Let me know if anyone has answers to any of the above
questions or if you have ideas on the following suggestion:

Maybe I could try to convert my older DOS PC to a Windows
98 PC (but only Win98, because for other reasons that are
too lengthly to explain, related to software compatibility
with Win98, any other Windows system will not due on that
older DOS PC); and then MAYBE I could run Symantec's PC
Anywhere on the Windows XP and Windows 98 PC ... AND they
could MAYBE even both allow file-transfers and DOS windows
to appear in their windows sessions during the remote
session????? DOES ANYONE KNOW WHY "PC Anywhere" WOULDN'T
ALLOW THAT TO WORK ??????

Thanks.
