We've recently started to implement windows 7 on any new machines we purchase. Problem is that our webmail hosted with MS exchange 2003 (sp2) has issues with a combination of windows 7/vista and IE7 or 8. We were unable to compose emails before, as it would simply appear with a red x. where your text editing field was supposed to be.
I applied KB924334 hotfix on one of our front end servers (we have two) in order to test it. Of course, the result was that we could finally see the text editing field, provided the new S/MIME was downloaded and installed. However, IE would then instantly crash when you attempted to send an email. The recommendation from another website was to apply kb924334 on the back end server as well. Immediately after this was done, OWA now appears with graphical glitches. The buttons aren't functional, both in basic and premium mode.
I mentioned earlier that we had two front end servers. The second one I hadn't touched, and it seems to work perfectly fine, only because I moved the latest exchweb folder version from the back end server to it. The same attempt to the defective front end server didn't bare the same results, sadly.
I've also tried restarting the app pools in IIS management, as well as the IIS service itself and its dependencies. None of this of course, has worked.
What I find odd is that this all started when I installed kb924334 on the back end server, while an installation of the same hotfix did nothing when installed on the front end server only.
As a result of all this, I've removed the hotfix on both servers and all is well. Google doesn't have much on this issue except that the reason windows7/vista with ie 7/8 doesn't work for my current setting is because DHTML is no longer used for OWA.
Any ideas would be much appreciated.
