Hi I have Exch 2010 Environment of 4 servers. 2 are MBX/HT and 2 are CAS. My DAG was working fine before i created CAS array. One member of my CAS array was File Witness server for the DAG. I dont see File witness share folder either. My CAS array is made up of Win 2008 NLB clustering.

My question is, should i add 2 of my CAS array server as main and alternate file witness share servers on my DAG or shall i remove and reconfigure a new DAG?

You need to remove and re-create the DAG, however, I would suggest that the NLB name is not the best name to use for the File Share Witness.

Thx, initially i tried to use nlb name and it didnt work. then i used name of a member of nlb and its working fine now. should i use second member of my nlb as an alternate file witness share. Would it be ok? im little nervous about this as im not aware of the repurcussions.

It needs to be a specific server, using the NLB name will not work.
A single FSW is all that is required, I am not sure you can add a second, I have never tried it.
