And do the old reset winsock procedure. Hint at http://support.microsoft.com/kb/299357
This isn't really the correct forum but I can't find one for protocols, so...
FTP worked fine on my workstation on Monday. I haven't installed or changed anything since, but now every time I try to open an FTP connection it is immediately closed by the host. This happens:
o On all hosts, including ones on my LAN (so not a NAT or connection error).
o On all software. I use CuteFTP but this happens using command-line FTP as well.
o Before I'm prompted for a password.
This doesn't happen on other machines on my network, so I'm finding this pretty strange. No other problems with the machine.
