(All reports say it's an absolute nightmare to get working)
Even if the network-share is on the machine you are using as a client, you have to use the "full Path" in the ini file:
//mymachine-name/myfolder-name
And try to use an "easy" folder ... and certainly not one in User-Directory, if you can help it ...
(but see the comment at the top ... I see very few - if any - posts proclaiming anyone has it working 100%)
Last I saw Ducie on here was trying to get this to work ... never saw him post he had it working though. A few others on here might be able to help ... the big mod teams are using it (but I think only for merging ESPs into ESM files ... and only 1 team member actually using the VC system)
