Today, Disk space on one of my company's server was Full. As a Massive database was growing more massively, we were moving some databases to another drive. At one point the SQL Server got stuck.After rebooting the server, noticed that SQL Server Agent was disabled.  Message shown in the Object Explorer was SQL Server Agent (Agent XPs disabled). Well, I had seen this message a few times on other Servers before this but had ignored it as there werent any important Maintainence Plans or Jobs Scheduled. But this time that Server was loaded with important Jobs and Maintainence plans hence had to find out a Solution this time .
