For example: > _ldap._tcp.dc._msdcs.LG.TS.HAL.CA.QSFT
_ldap._tcp.dc._msdcs.LG.TS.HAL.CA.QSFT service = 0 100 389 dc-plg2.lg.ts.hal.ca.qsft.

2 - If domain controller are available, try restarting vasd to see if another server is picked up. Then re-run the vastool status command to check if it reports healthy.
3 - Note the information reported by this command : /opt/quest/bin/vastool info servers Rejoin the server to AD : /opt/quest/bin/vastool -u ADUSER join -f YOURDOMAIN.com
Do the vastool status and vastool info servers commands again and compare output. Sometimes there is a problem with what AD site the clients are contacting.
Remove the /var/opt/quest/vas/vasd/.force_disconnected_mode file and restart the vasd process
