I'm wondering if it's possible to setup the File Share Witnessfor a CCR Exchange using aHub Transport that isusing Windows NLB with a second Hub? I assume that it should be on only one Hub, to achieve the third vote, but are there any issues with this scenario? Thanks.

Hi, Yes one server should be enough, it can be the HUB transport but you can also host it on another Windows Server for example a file server Regards, Johan visit my site: http://www.johanveldhuis.nl

if the File share witness stops working you can always create a new file share on another server http://technet.microsoft.com/en-us/library/bb124922(EXCHG.80).aspx this article is also good info http://msexchangeteam.com/archive/2008/04/03/448615.aspx

Clarify: You want to know if we can setup FSW on NLB Johans right, you can host FSW on any computer as long as it has Windows Server OS We do not recommend install FSW on NLB. Its always recommend to deploy FSW on Hub as it will easy from manageability perspective Workaround: a. Create a FSW b. Create a CNAME record and point to one node c. When a node on NLB fails, it requires CNAME record to be pointed to new node d. Restart IS on CCR Notes: Risk is when NLB node and one of the CCR nodes fails
