Not as a regular maintenance issue. I'm not sure it's really a problem in the first place. Records should get expired with their TTL. Even if MS-DNS is holding on to data longer than it should, I would expect the required monthly reboot for any Microsoft product[1] would take care of that for you. I will very occasionally clear DNS cache if there's a problem that appears to be due to stale resource records. (You can tell this is the issue if an authoritative server answers differently vs your cache.)
