Clustering -- Quorum -- How do you configure a file share witness on another domain?

Hi There,

I am setting up Clustering in a Windows 2012 (R1) environment.

I have a domain [myDomain], two servers on two sites, they belong to the myDomain. They have two services clustered and this is working.

I now wish to configure the Quorum File Share Witness option. Due to too many complications to explain here I need the File share to be on another Domain (outside my control ... a long story) so lets say the domain is called remoteDomain.

When i am configuring the Quorum option in the cluster wizard and I enter this share i get a "is not valid share path" NOW for info using normal windows explorer i can get to this other share be it i have to enter credentials in the usual windows pop-up box but it does work.

Am i to assume that the file share witness must be on the same domain as the cluster? If not what do you do to configure this as at a lit of a loss.

Sorry if i have just asked the daftest question here ;)

Thanks,

Steve
