I have MOSS2007 and a mix of XP, Vista and a few Win 7 64 workstations. All of them are running the Army Gold Master operating system, and Office Professional 2007. Updates are done using WSUS. I have full control permissions on the site and on another site I am site collection admin so it shouldn't be a permissions issue and since i am on 2 different site collections, it shouldn't be some weird site collection corruption issue either. (although they are all the same server farm) The entire server farm and all site collections and sites are https and require CAC authentication. When I try to upload from the slide library PowerPoint opens with a browse, I select ppt or pptx file it opens publish slides window, I select one or all and the publish to is correct I click publish, and widows security asks for my credentials, I select the proper certificate and then I get a https://<URL> is not accessible. Either the location does not exist or you might not have permission to use this network resource. Click OK, and it just goes back to Publish Slides window. clicking again just produces the error no request for certificate. I am suspecting that this is either related to some security setting in HIPS or firewall, or it is some really simple fix like a site feature that I don't know about. If anyone has any ideas, I would greatly appreciate it.

Hi, This is a very a complex setup actually. There are a lot places this can break. If it gets past the firewall, then it is possible that PowerPoint is not passing the CaC information. We would need a netmon to see that, however since you are running SSL this will probably not be possible. You could possibly gather some information via Fiddler(www.fiddlertool.com) and select the decrypt SSL option and see the HTTP(s) traffic going along. You may see a whole bunch of 401's. If so, CaC is probably not being passed. If you're seeing a different URL that is trying to connect to then when Proxy/AAM/Firewall can be suspect. I hope this helps.
