STUFF YOU CAN USE!! Finger Saving Good – No Touch Administration

  • Article

Remote Desktop has changed the way we interact with our servers. However if you have a farm of 50+ servers…heck even 10 servers, having to Remote into each server can not only be time consuming but cause your fingerprints to wear off. Utilizing tools such as WMI (Windows Management Instrumentation), For Loop and PSEXEC you can administer a large number of servers remotely with minimum joint pain. The Examples below go from beginning WMI usage to more advanced techniques. These scripts are meant to be a base to start from and help you build a powerful toolset.

Index of scripts below:

Example 1: A basic WMI Script to warm up with.

Example 2: Collect Connection and Processor Information from 2 separate server lists and email the results.

Example 3: Need an inventory from a large amount of servers and write the results to a file? Personal Favorite!

Example 4: Have an unnecessary service which you need to stop and disable across your environment?

Example 5: Ever wanted to send an email without configuring Outlook Express to test an SMTP server?

Example 6: Need to know who is a member of a group across your environment?

Example 7: Use a For Loop in the command line to execute a command across multiple servers.

Example 8: PSEXEC – Every Engineers necessity.

Example 7: Using a For Loop:

For /F %i in ( <YourServerList.txt> ) Do xcopy d:\test.txt \\%i\d$\test.txt

You can replace xcopy with any command you normally would use on a single server.

Log Parser:

For /F %i in ( <YourServerList.txt> ) Do logparser –q:on “Select Count(*) from \\%i\e$\wwwlog\W3SVC1\ex*.log where sc-status = ‘404’

Find Current Connections:

For /F %i in ( <YourServerList.txt> ) do psexec \\%i netstat -an | find "ESTABLISHED" | FIND /c ":80"

Example 8: PSEXEC:

https://www.sysinternals.com/ psexec.exe provides a powerful tool to remotely run applications.

Run a Command Prompt remotely:

psexec -u <Domain\User> -p <password> \\ <ServerName> cmd

When you are done, type Exit.
