RSH and RCP on Windows 2008
You may face issues while using RSH and RCP in Windows 2008. Analyzing the network trace will reveal that RSH has trim down the username while sending the query. As a result the RSH authentication fails. One workaround to this issue is to download Services for Unix 3.5 from http://www.microsoft.com/downloads/details.aspx?FamilyID=896c9688-601b-44f1-81a4-02878ff11778&displaylang=en and extract RSH and RCP binary from it.
Then you can easily replace (copy and paste) these binaries with the one’s present in Windows 2008. I tested it in one of the environment and it works!
