I have problem when using network because I have no problem when connect using "." but I have difficulty when using "127.0.0.1" !

Event long errors are these :

1- Length specified in network packet payload did not match number of bytes read; the connection has been closed. Please contact the vendor of the client library. [CLIENT: 192.168.128.76]

2- SQL Server could not spawn FRunCommunicationsManager thread. Check the SQL Server error log and the Windows event logs for information about possible related problems.

3- Could not start the network library because of an internal error in the network library. To determine the cause, review the errors immediately preceding this one in the error log.

4-TDSSNIClient initialization failed with error 0x50, status code 0x1. Reason: Initialization failed with an infrastructure error. Check for previous errors. The file exists.
