In a web system of VB. NET + Asp.net, when using the SQL2000 database, sometimes a strange phenomenon occurs during running. When a user logs on, the logon interface is actually another user.

A Web System of VB. NET + Asp.net that uses the SQL2000 database. At the beginning, there were dozens of connected users, and there was no problem after the first year of operation. Later, the number of connections increased to about 800. Now, a strange phenomenon occurs occasionally during the operation. When a user logs on, the logon interface is actually another user (most of the users are currently online). However, after some operations, such as query and refresh, the user will return to normal.

Please help. Thank you.
