Windchill Certificate error Problem: When a user attempts to access Windchill he will recive an "certificate error". It will tell him this is not a trusted site and that he should not attempt to access it. Deny is the first choice followed by Allow (not recomended). This can cause other errors with internal components. Solution: You need to add plm.bdk.com to the trusted sites in Internet options. Open IE Select Tools --> Internet options Select security Select trusted sites deselect the check box about https add plm.bdk.com select OK close IE If the user is still having issues you may simply need to disable the certificate errors Open IE Select Tools --> Internet options Select Advandced Scroll to the very bottom deselect the checkbox titled "Warn about certificate address mismatch" Select apply close IE Another less common reason this can happen is that the user's system time and date are not correct...it might be helpfull to add this. 06/30/2010 -Mitch
