If you tried configuring your SMTP server on port 465 (with SSL) and
port 587 (with TLS), but are still having trouble sending mail, try
configuring your SMTP to use port 25 (with SSL). 

Also note that with Gmail, you can send and receive messages up to 20 
megabytes (MB) in size.

Second Query:
As of now The Log_IP.txt file is created in a folder in C drive.
I wish to create this file in a server or another PC(say admins computer), how to achieve this?

I want this file to be created only once, say the file is created in the server or admins system.
each time a user logs on, the logging needs to be appended on to that file.

 'From MSDN
In members that accept a path, the path can refer to a file or just a directory. 
The specified path can also refer to a relative path or a Universal Naming Convention (UNC) 
path for a server and share name. For example, all the following are acceptable paths:

    * "c:\\MyDir\\MyFile.txt" in C#, or "c:\MyDir\MyFile.txt" in Visual Basic.
    * "c:\\MyDir" in C#, or "c:\MyDir" in Visual Basic.
    * "MyDir\\MySubdir" in C#, or "MyDir\MySubDir" in Visual Basic.
    * "\\\\MyServer\\MyShare" in C#, or "\\MyServer\MyShare" in Visual Basic.
