We have recently had this complain from our various Shared hosting as well as Dedicated Server hosting clients that MSSQL Webadmin ASP .NET Enterprise Manager is having a virus / trojan on it. When the first complain arrived we too thought that there seems to be a problem with the server and might be MSSQL Webadmin ASP .NET Enterprise Manager has got an injection in it. But after receiving too many complains from most of our dedicated server clients we started investigating the problem and now we knew that this is something that has happen globally. After viewing MSSQL Webadmin ASP .NET Enterprise Manager on Plesk server it looked as the picture below:

This has been a regular problem with most of our Windows dedicated Server Clients as well as Windows Shared hosting client that has Plesk 8.4 installed on them, specially for those who need write permissions on web user for the ASP .NET/MSSQL and PHP/MySQL application, that the write permissions on the folder get removed own its own without any changes being made by us or the client. After allot of scratching and investigation we were finally able to reveal the secrete about the permissions issue. The problem was not with Plesk but the way we use to set permissions on the folder.
While I was searching for the solution I found the KB articel on Parallels sites below:
It is very easy to block a single IP address on a Linux server but Windows Default firewall doesn’t allow us to block a single IP address on the server or for particular ports. However Microsoft released this and introduced IP Security Polices in their Local Security Polices option in the release of their SP2. But most of us are not aware of this option and we mostly adopted third party firewall and pay for their heavy license. However Firewall onl Windows 2008 Server is far more advanced than that on Windows 2003.
It would not be the case now as I have listed detailed steps along with the images on how to block IP using the IP security policy in Windows. This option is also available in XP as well as Windows 2003 Server edition.
How to BLock IP Using Windows:
You can either open MMC from START >> RUN >> MMC and add a new Snapin for IP Security policy with steps below:
EFS can be used to encrypt SQL Server 2005 data files and folders. EFS is supported on Windows 2000 and later operating systems with New Technology File Systems (NTFS) formatted drives. EFS uses a combination of symmetric and asymmetric methods to provide transparent SQL Server 2005 data encryption. On Windows 2003 Server and newer operating systems, EFS by default creates a random File Encryption Key, which is a 256-bit AES key to perform data encryption.The File Encryption Key is then itself encrypted with the user’s public key and stored within the encrypted file or folder.
To encrypt SQL Server 2005 data files and folders using EFS, follow these steps:
1. Stop the SQL Server service.
2. Log out and log in using the SQL Server service account credentials.
3. Right-click on the file or folder to be encrypted and select Properties | General Tab | Advanced.
