Hello, so this is a follow up to the assistance that was provided to me yesterday about checking to see if the SNMP service was installed across multiple servers. I was able to gather a list of devices that require the SNMP service to be installed,
and (thankfully) most of them are Server 2008 machines. The pre-2008 machines I will just hit manually, since there are less than 20 of them, and to minimize confusion, and a lack of powershell knowledge from my side.
I have approximately 120 servers that will require the service to be installed onto them, and was looking to do this via powershell. Luckily, I was able to find this great script online, and I have tested it with my own variables inserted, and it works great (for one server, ran manually on it). I was wondering if somebody could help me figure out how to get the script to do the following two things:
1. Install the SNMP service to multiple servers from a text file (I attempted this with the get-content).
2. Output the results to either a text file or a csv file (also tried this as can be seen below).
Here is the script, with what I tried (and failed). The only two lines of code that are mine, are the very top one and the very bottom one, I will bold them to indicate that. Thanks for any help that may be offered.
