The system files provided with Windows Server 2003 have a Microsoft digital signature, which

indicates that the files are original, unaltered system files, and they have been approved by

Microsoft for use with Windows Server 2003.

All drivers included with Windows Server 2003 are digitally signed by Microsoft. You can verify

that third-party drivers have met the WHQL standards and that they have not been modified since

they were tested. To ensure that device drivers are compatible with Windows Server 2003, look

for vendors offering drivers signed by Microsoft.

Checking for Digital Signatures

Windows Server 2003 includes the File Signature Verification tool and signature checking to

identify files that have been signed.

With the File Signature Verification tool, you can determines whether a file is signed and do the

following:

• View the certificates of signed files to ensure that a file has not been tampered with after being

certified.

• Search for signed files in a specific location.

• Search for unsigned files in a specific location.

To run the File Signature Verification tool, click Start, click Run, and then type sigverif and click

OK. The File Signature Verification too opens. To customize its behavior, click Advanced. The

Advanced File Signature Verification Settings dialog box provides the following option tabs:

• Search enables you to search all drivers or specify the name and location of the driver search.

• Logging saves the program's results as a log file. You can provide a file name and determine

whether to overwrite or append to an existing file and view the existing log.
