It will work on any other port (991, 989, etc) but not on port 990. Looks like port locked by OS for some other process. Any help greatly appreciated.

  Re: IIS7, FTP7 - FTPs on port 990 Reply Contact In my case I have to run 'open 10.10.10.10 990'. I get response "connected to 10.10.10.10" and than "connection closed by remote host'. However, if I change port to 991 I get regular response: Connected to 10.10.10.10, 220 Microsoft FTP Server, and prompted to enter user ID and password. (FTPs site requires SSL). BTW Windows firewall completely off during each procedure.

You sure you change it to 990, then stop / start IIS ftp service ? also try to do it on the localhost... open localhost 990. Cheers, Bernard Cheah

Case is still open with Microsoft w/no answer. Again, it worked fine on beta code and stopped working after going to production release.

  Re: IIS7, FTP7 - FTPs on port 990 Reply Contact Geezzz.. i can repro on my Vista x64 :) 991, 993 works. but 990 - connection closed..... but binding is correct for ftpservice... but I think I know why. this is because 990 is meant for ftps connection. the default secure ftp port. so is like port 443 for HTTP. if the IP is binding, 443 is kinda like reserved for ssl usage. even you are not using it but if you do - it is only for https, not http.

  Re: IIS7, FTP7 - FTPs on port 990 Reply Contact  While Microsoft Techs still scratching their heads to figure out why FTPs over 990 does not work on RTM0, one of my colleagues  found  solution by trial and error. FTPs on port 990 on FTP7/IIS7 on 2008 server works only with clients that support implicit ftps, which is older implementation of FTPs but still 'widely" used (Microsoft FTP7, RTM0 implementation in this case. Why did they have to change it from BETA to RTM0). Tested with Ipswitch WS_FTP Pro 2007, older versions do not have Implicit/FTPs option and latest Core FTP LE. The only problem is that server is VERY unstable for this service.

Your problem is ftp on 990 not ftps on 990, right? ftps on 990 should works. Cheers, Bernard Cheah

Service on port 21 works fine service on port 990 requires client that supports implicit FTPs (Microsofts' implementation of FTPs). On another note: service on port 990 is very unstable.
