After changing your Windows password when using the PGP WDE Single Sign-On (SSO) feature, the password is not synchronized with PGP BootGuard and you must use the old password to authenticate at the PGP BootGuard and Single Sign-On no longer functions properly.
This can be caused by a file permission limitation on the PGPWDE01 file or by the location of the PGP entry in the Provider Order list for Network providers in Windows.
To check PGPWDE01 file permissions
If the SSO feature fails after changing your Windows password, check the permissions for the PGPWDE01 file located in the root of the C: drive.
The Authenticated Users group needs to have Modify permissions for the PGPWDE01 file. If necessary, modify the permissions for the file, logging off and logging back on to Windows will cause the PGP Tray to update the PGPWDE01 file.
PGP Network Provider Connection
In some cases, other third party Network provider connections may interfere with the SSO feature of PGP WDE. Try moving the PGP Network Provider connection above other third-party connections in the Network Provider Order. Use the steps below for your operating system.
Windows Vista & Windows 7
USB disk or SD card
If a USB thumb drive or SD card is inserted, a conflict may occur if the USB or SD disk is detected as Disk 0 on the system. Confirm the Windows system disk is Disk 0 in Disk Management. If the USB or SD disk displays as Disk 0, remove the disk, reboot the computer, and then change the Windows password.
