In order to troubleshoot, we will need your entire ACL / http_access portions copy/pasted, with sensitive portions edited, if need be. >>> Damian Teasdale <damte@xxxxxxxx> 2/23/2011 1:12 PM >>> Here is our environment: LAN users all go through the proxy for internet access, works fine. A few users need access to RDP to an external partners Terminal Server. The terminal server has a Certificate issued by GoDaddy.com. When the users on the LAN attempt to connect to the external Terminal Server I don't think that they can authenticate the certificate. I watch the access.log and I see these lines written: 1297896161.739 70 192.168.x.xTCP_DENIED/407 1962 GET http://certificates.godaddy.com/repository/gd_intermediate.crt - NONE/- text/html 1297896161.742 0 192.168.x.x TCP_DENIED/407 2158 GET http://certificates.godaddy.com/repository/gd_intermediate.crt - NONE/- text/html 1297896161.745 2 192.168.x.x TCP_DENIED/407 1962 GET http://certificates.godaddy.com/repository/gd_intermediate.crt - NONE/- text/html 1297896162.086 319 192.168.x.x TCP_DENIED/407 2055 GET http://www.download.windowsupdate.com/msdownload/update/v3/static/trustedr/en/authrootstl.cab - NONE/- text/html 1297896162.089 0 192.168.x.x TCP_DENIED/407 2251 GET http://www.download.windowsupdate.com/msdownload/update/v3/static/trustedr/en/authrootstl.cab - NONE/- text/html 1297896162.091 2 192.168.x.x TCP_DENIED/407 2055 GET http://www.download.windowsupdate.com/msdownload/update/v3/static/trustedr/en/authrootstl.cab - NONE/- text/html I have tried putting in some acl's for this but it doesn't seem to make a difference, here are the acl's as I have them setup: acl GoDaddy dstdomain .godaddy.com http_access allow GoDaddy There are a lot of other acl's that we have setup but did not include them all, but could if needed. Any ideas about how to get this working? As a work around I have put in a separate ACL to allow that LAN computers IP address direct access and it works, but this is not ideal.
