Hi, I have a question running around my head lately and I couldn't find any written article or KB denying or confirming what I going to ask: Exchange version: Exchange Server 2003. OS version: Windows Server Enterprise 2003 Why when an Exchange database is set with Circular Logging is still needed to reset its Log Sequence? Shouldn't it be reset every new circle of logs, although it may sound redundant? Or even reset on every full backup? Thanks in advance. Agustin.

Because log sequences are generated sequentially. >Shouldn't it be reset every new circle of logs, although it may sound redundant? If that were the case you'd have to stop the Information Store service and delete all the log files and the checkpoint file to reset the generation numbers. >Or even reset on every full backup? Backing up a database doesn't stop updates. New log files can, and are, created while the backup runs. --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP
