Some Additional Info

the doucmentation says that there wil be a hostkey file in Isolated Storage of the Service account runing biztalk service on first run , later this is used to cross check.

before the IP of SFTP was change the SftpHostFiles.config(Containing a correct hostkey) did exists but i deleted them to re-bin and now when i start the process those the file are not being created . The SFTP servers IP address is changed but i am using the host name and not ip , trying ip also does not work ...Any idea what could be the issue .

Thx in advance
