I have a situation where the old 2008 R2 RDS server is going to remain in place for a while.  The users are on a new 2012 R2 RDS setup with a session collection and an rdsh server farm with 3 rdsh servers.  The old box has an old version of Adobe Acrobat Standard, version 9, which can't be installed to server 2012.

For various reasons they are not upgrading the version yet, but it works out, the app has been installed on the 2008R2 box for some time, so i simply published it, deployed it as an MSI, installed that MSI to the 2012 boxes, users think they are running version 9 on the 2012 box, for the most part it's a really great resolution.

One problem, every single time the launch the Adobe 9 icon they are prompted for credentials.  both servers are on the same local AD domain, they simply enter their domain creds every single time.

Any idea on how to mitigate this as i'm sure they will grow tired of this effort before too long?

Thank you.
