Hi, i have 2 problems: 1. after updating TSM Server 3.7 3.8 -> 3.7. 4.0 the adsm.exe fails to start with a dr. watson error. TSM Server is running on a Windows NT 4.0 (SP5). 2. the performance of the Backups is very bad since we updated from ADSM 3.1 Level 2.40 to ADSM 3.7. cache hit percentage is < 96 %. The Server is a Compaq Proliant 3000 / 600 MHz Xeon / 1 GB RAM /WinNT 4.0 (SP5) i hope anyone is able helping me solving this problems thanx Gary
