Hi,

We have a third party web application (ASP) that when it is being accessed internally (within corp network), it works fine with IE8 or IE10 with Compatibility view.  However, when we access the web application via VPN, we are getting an "Internal Error: Unhandled error loading XML document (file) ../taskmanager/task-manager_preformat_email.xsl, error:System error -2146697189".  After digging and troubleshooting, I found out that this .xsl file is supposed to be downloaded to the C:\Users\user_name\AppData\Local\Microsoft\Windows\Temporary Internet Files folder.  However, it doesn't when in VPN. I tried to change some settings in IE and registry as well but no success.  

Anyone has idea?

Thanks.

Is your vpn set to push all traffic through it or only for local networks?

Are you referring to split tunneling?  I believe that we do not allow split tunneling (as per our server group).

Yes that is what I was referring to.  In other words it's as if they're on the network once they've connected.

any different configuration with proxy?

No difference in the proxy configuration between a vpn user and a user on the lan.  All users get redirected to the proxy for internet access.  They are not directed to the proxy for intranet access.

As per our Server Group, there was a problem with the transparent proxy (Configuration got reverted back to what we had when testing PaloAlto).  Not sure if it could have been messing you up on the vpn side.

After testing the web apps via VPN, the error disappeared.  However, we are still getting an application error where it seems that .js file unable to read .XML files.  Comparing the IE temp files folder between LAN access and VPN access, there are .XML files not downloaded via VPN.  I've asked our Server Group to check proxy configuration again, but I was told that there's nothing to check. "They turned off what got turned back on.  So now vpn users are no longer filtered through websense for internal sites."

The request for the XML files may still fall outside this condition and be filtered.  Are the XML files located on the internal network?

Yes, The XML files are on the web server (internal network) and gets cached.  We are till trying to resolve the issue.  We found one old laptop that works via VPN.  I was given another laptop loaded with minimum software (VPN, IE8) a while ago, but it did not work on this laptop via VPN.

Our issue has been resolved.  After discussing with the vendor's technical experts, we have to modify the application code where an Outlook viewer object does not work with VPN.  The vendor was using an older version of the Outlook viewer object and after modifying all files using a newer version of the object, then our web apps worked via VPN.
