Can’t see Global Address List (GAL)

Environment: W2K Adv Srv w/AD active;E2K.
Recently recovered from STOP:c0000218 SOFTWARE registry corruption; Reinstalled E2K using the /DisasterRecovery switch, applied latest service packs for OS and E2K. Users cannot see the addresses in the GALfrom within Outlook (2k, XP)…a ‘FIND’ works…manually typing the display name obtains the correct email address.
The GAL in E2K System Manager shows an empty right pane. A New Address List cannot be built from the GAL.
Anyone been through this scenario or similar or simply know the answer?
Thank you in advance for your assistance.
