Dear All, I am using exchange 2000 server on windows 2000 server. I have been using it for the more than last 2 years. Recently I started facing problems. Every Sunday at around 2:00 AM it generates lots of log files in MDBDATA folder which eats up all the space in C drive and dismounts the database. I had to manually delete the log files and mound database back to make exchange available. I don't remember changing anything in exchange. What could be the issue? Can any of you guide me? Sincerely, Shamshad Ahmad
