500 Out of sockets, Try again later!

There is a problem with the server's configuration or server's system you are connected to. The server's system site has a maximum of N connections on the TCP/IP layer (Windows 9x: N=100). The maximum number of connections is easily reached when 20 users log in to the site and each user uses about 4 connections. It could be that the connections are not closed right after the user quits.

There are hidden MSTCP registry settings where the maximum number of connections can be changed. Further details on hidden MSTCP registry settings can be found in the the Microsoft KB article: Q158474

Change the maximum number of connections by editing:
Hkey_Local_Machine\System\CurrentControlSet\Services\VxD\MSTCP MaxConnections = 32-bit number Data Type: DWORD

For Windows 98, the Data Type is a String value that specifies the maximum number of concurrent connections. The default number is 100.

Note: If the DWORD MaxConnections is not there you will have to manually create it in:
Hkey_Local_Machine\System\CurrentControlSet\Services\VxD\MSTCP
Set the MaxConnections DWORD to 500.
