The problem is: We have SE (6.5.54) on two stations, the shop office "Host" where most orders are written and most shop business is done, and a "workstation" in my office (GM of the dealership, mostly for oversight, approving estimates and helping out where/when I can). We have access to five electronic catalogs, and all five work fine on my "workstation". However, the FirstCall and RepairLink catalogs both throw certificate errors when opening on the "Host" machine in the shop.
The FirstCall catalog opens the browser window and warns "Warning: revocation information is not available for this site" and then asks if you wish to continue. If you click on details, it mentions something about a GoDaddy certificate issuer. You can click on the OK/Continue button, and you get about 12-15 identical pop-ups in a row. But if you click through them all, then you get the FirstCall site and catalog and it works just fine. You can transfer your parts to an RO, and even order the parts electronically with no problems. After you have gone through that ordeal once, I believe you will not receive that error again until you exit SE and then re-open it. When our Independent Rep encountered this while setting us up, he called tech support who said they'd never seen it before, must be network or computer settings on our end. I told him I would have our IT people get on it. Two weeks later, having exhausted every conceivable update/tweak/setting on both the machine and our SonicWall firewall, they intercepted the web address the catalog was opening, and copied that address directly into Internet Explorer on the same machine and it opened just fine, with no problems/warnings whatsoever! They tell me that SE is in fact using Explorer to open the catalogs, so if it works in regular IE it should be working in the mini-browser within SE unless there is a problem with some library it may be supposed to load?
Today, I noticed for the first time that our Rep hadn't set up the RepairLink catalog on the shop machine for some reason, although it was installed and working on my "workstation" (we are still figuring all of this out, just transitioning to electronic R.O's). So, I downloaded the catalog installer, closed out SE and installed the RepairLink catalog. Opened up SE, turned on RepairLink and tried to open it. This time, instead of a pop-up, I just get a full white page with a warning that there is a problem with this site's certificate, and it will not allow me to go any further.
I have logged onto the machine as the domain admin, to eliminate the possibility of it being a "privileges" issue, and exact same result. Also, the shop user and I have identical user profiles/domain privileges. I know SE isn't supported on domains, but since it works fine on my workstation I would be shocked if the domain was the issue. My workstation is accessing the database on the "Host" machine over the domain.
Again, the other three catalogs work perfectly in the shop, as does the FirstCall once you've clicked through 15 billion warnings and they all work fine on my workstation. Anyone see this before? I apologize for no screen shots, it's 11:30pm here, I have been searching the forums and knowledge base since I got home and didn't take any screenshots at work. But I decided I wanted to try to get the ball rolling here in case it would be any help. If anyone thinks screenshots will help, please describe what you want pics of and I'll figure out how to attach them. Should I just try tech support again? They seemed a little dismissive when my Rep called them, and once when I called them (on a different matter). At that time, it did look like a likely network/permissions problem. I'm beginning to wonder if something glitched on the catalog installs, but I can't figure out how to uninstall them to try it again.
Sorry about the wall of text! At least I used paragraphs!
