Home Forums Discussions IT, Networking, PCs and more Losing connectivity in Peer-to-Peer networks

For those of you who use peer-to-peer networks, you may find that your workstations are no longer able to communicate suddenly. Usernames and passwords to log on to file shares on other peer machines no longer work.

The reason is twofold:

1. Two or more of your workstations have the same SID. SID (Security Identifier) is a unique number every Windows computer has. The reason you may have one or more machines with the same SID would be if your IT guy cloned the other machines from one without properly using sysprep, or if you purchased several machines at the same time from a company like Dell or HP with Windows preloaded and the OEM did not change the SID from the clone.

2. The latest update from Microsoft prevents machines with the same SID from communicating.
