I was having an issue with UNC based disk storage as being an invalid path. Based on a suggestion I received here, I changed over to ISCSI for disk based. No problem setting it up and accessing it on the server. BE Test runs are successful. However, when I go to run the actual job, it hangs at "Active: Queued" indefinitely. I've deleted/recreated the storage, jobs, and removed/reinstalled the servers. No fix. Lots of unresolved forum threads on this issue. Any guidance is appreciated.
