So, at least I know that permissions are ok. Drive where UNC folder is 1TB. Total table size is less than 70 GB. So, we have plenty of space. we have other replication in the environmet with more than 1 TB data synchronizing. So, I know size is not an issue. It probably has something to do with time elapsed while snapshop agent bcp data out. But what?
What type of storage device does this UNC point to? An external USB harddrive, a NAS? a SAN? Etc?
How much time has occurred when you receive the error that the specified network name is no longer valid?
Sounds like your storage device is having issues, but you have a couple of options: 1) you could create multiple publications (say with articles A-M, N-Z), then create 2 different snapshots. Or you could use your existing publication (adding in say 80 articles to start with), generate your snapshot, then go back and add the remaining articles, then start the snapshot agent again manually (this actually works quite well however, requires that you have tweaked a few replication settings not inherent in the default set up for transactional replication)
