We are having an issue with Session.SessionID not getting a new ID for multiple users. A few users from different IP locations get the same Session.SessionID causing wrong Session Variable values to be returned. One computer is getting the same ID between Chrome and IE.
The server was restarted and the computers are still receiving the same SessionID. We changed from SQL Server Session to InProc Sessions and the same SessionID is still being generated for the same users.
We are just setting Sessions Variables and Not using forms authentication as this is being handled separately.
The server is Windows 2012 with IIS 8.0.
Please let me know if you need additional information.
