I have recently upgraded one of our instances of UAG up to SP3 and all went well. However, upon connecting from a Win8 (Pro) tablet, using IE in desktop mode obviously, I get the following error:

Forefront UAG client components cannot run. The script signature public key file cannot be downloaded from the server. This might affect your site experience, depending on corporate access policy

I can "Ok" past this and log in ok but this results in endpoint components not running and no subsequent access into apps that require it.

I am also running a test instance of UAG SP3 and the same device can connect fine to this instance (endpoint components install and run fine). The test box is running an identical configuration - the only difference being its name and SSL cert.

Has anyone come across this error before and have any idea how to solve it? Much appreciated.

I'm doing that tonight (although only because of KB2831573). Having read the notes I couldnt see any direct correlation between my issue and the bug fixes mentioned in the roll-up.

That said, I appreciate the advice and it will be interesting to see if there's an unexpected (but welcomed) side effect of this roll-up on my primary issue.

I still think I'm looking at a rebuild - I cant get away from the fact that my test instance (sans SP3 Rollup1) works perfectly from any client.

Thanks for the advice. Will post up progress.

Hi Mindvor,

I have the same problem but only affects win8 clients. Win7 clients work fine.

Any progress?
