We installed it with just one glitch.
After we installed it, no one could access GroupWise or WebAccess. Turned out the patch put a duplicate ip address in the sys\etc\hosts file.
We just rem'd it out and all was perfect. Make sure you do reboot the server when you are finished or you'll get a couple of errors.
Our users like it because they can now click on the globe to read mail and it opens normally, instead of minimized on the taskbar.
It took care of about a dozen items we wished were in place, such as undeletable blob files, and speeding up printing.
We even added a /bl to the GroupWise desktop shortcut to keep the GW splash screen from loading and that really speeded things up.
Now, if I could get WebAccess (no enhancement pack) to print out dates and times, we'd be good to go.
