Owa not working via exchange 2010 sp3 with dag

Hi,

I have exchnage 2010 with sp3 install , dag avialable ( 2 servers ) and 2 HUB/Cas ; we are using Tmg to publish owa.

I noted that search via owa not working after we installed sp3 while it works on outlook.

I deleted catalog files and re-start exchange indexing useless

Any other ideas?

Thanks
