Hi guys . We are having sporadic problems when 1/2/3 users can't login, when other 100 users have not this problem . It happens once in 2-3 weeks. It's not configuration issue I think because it was working on those users and nothing was changed on their profiles, and it will work after couple days again with no intervention from my side. I am trying to figure it out is it license not enough or communication btw CUCM and IM&P ?? How can I check it ? I see we have 255 enhanced 10.5 , 94 cuwl standard messaging, 197 cuwl standard available on Prime .
I see only one Dns unreachable warning on IM&P, but i dont think this may cause issue, i can resolve any names from IM&P from cli and ping .
some users says jabber was working and then it just automatically logged off , others can't login after pc restarts .
I also attached syslog screenshot with dns issue. How can i fix it ?
