The Server was unable to locate an encryption key

[lbauer]

This error occurs when an Export Edition Client tries to connect to an SOS Classic Version 3.5.3 Server that is configured to only allow 128-bit connections.

If the SourceOffSite Client is using a 56-bit encryption key, the Server should be configured to accept 56-bit connections. The Server can be configured to accept 56-bit connections in the General Settings tab of the Server Manager utility. To enable this, check the 56-bit option. After the Server is restarted to register the change, the Server will accept connections from both 56-bit and 128-bit Clients.

Please Note: Although the SourceOffSite Version 3.5.3 Server can accept existing 56-bit keys, it cannot generate new 56-bit keys for 2.x Clients. The Version 3.5.3 Server generates only 128-bit keys. If you wish to generate new Client keys, we recommend you upgrade to the 3.5.3 Client.
