Got a problem with my proxy server. Had a virus screw up my Exchange over the weekend, in the course of straightening that out, MS tech support and I screwed up Proxy. We were able to get it back installed, but now, while I can get out to any siteI want, certain files seem to be "blocked". No .gif files show up on web
pages, for example. Also, I cannot access any, at least all I tried, ftp sites. I don't see any filters or anything blocking these items. I tried to restore the folders from a previous backup, but that screwed up Exchange again. Any suggestions what to look for within the console?

Thanks for any help,

Nicole Sohenick

I doubt that it's proxy that is blocking these file types. Proxy does not have any filtering or capabilities that would filter out certain file types. It might however be IE itself. I would try installing IE 5.5 SP2 or IE6 and any applicable hotfixes to that and see if it solves the problem. It might be blocking ftp sites, but you could test this by turning off all packet filtering on the proxy server. If this fixes the problem, then you need to set up a packet filter exception for FTP port21. Hope this helps!

That answer would be good if only one system was having this problem, I don't think that we need to globally install these updates. However, the problem was fixed yesterday. I spent over five hours on the phone with MS Support yesterday, we unloaded some things and then reloaded them, I guess effectively restoring whatever settings were messed up. Thanks for your help though!
