Proxy limitation in GPO due to character limit

Archived from groups: microsoft.public.win2000.group_policy (More info?)

I see many posts regarding the same issue we are having that we are unable to
add more sites to our GPO proxy box due to a character limit in that box. I
am curious if there is a fix or patch for this as we need to add some more
exceptions and it will nto allow us?

Thanks in advance for your help!
