Self-solution of this problem was carried out.
Server-Side Composition currently used
'WindowsNT4.0Server(SP6) + IIS4.0 + CiscoPIX 5.1(2)'.
Client-Side Composition currently used
'Windows95 + WS_FTP LE'.
It stopped displaying an error message(Blocking Call Canceled), when a
server setup is changed as follows.
HKEY_LOCAL_MACHINE→System→CurrentControlSet→Services→(CardName)
→Parameters→Tcpip
The numerical value (576) was set as MTU.
I cannot understand why it solved. What was the cause? If you know
someone, please let me know.
