Domino Web Access 7 template problem

We were using Inotes60.ntf tempaltes for all mail users… Some of them are upgraded to Inoes6.ntf(domino web access 6). we don’t have any issue with them.Some of them are upgraded to dwa7.ntf(domino web access7) template. Now when they are accessing mails through web access , it’s asking for proxy authentication at the time fo login and log-off. We abrowse internet through proxy. If I reomve the proxy settings from IE it;s working fine .Same mail file if I downgraded to other templates, it’s not asking for proxy.

I’m very much confused to resolve the issue.

Anybody can help?

Thnx in advance
