The return values that a network provider can set include the following error codes.

Error CodesDescription

WN_FUNCTION_BUSYThis function cannot be reentered and is currently being used, or the provider is still initializing and is not ready to be called yet.

WN_OUT_OF_MEMORYThere is insufficient memory to complete the operation.
WN_NOT_CONNECTEDThe device is not redirected.
