I have seen many administrators who has difficulty to find members of local group (i.e. Administrators) for 100 or more servers. There are many scripts but they have their standard functionality and fixed output. When you try to modify the script as per your requirements, it become a big pain in a**.
Here are some links of good written scripts which can help you.

Disabling SMBv1 broke Network Login

As per the Microsoft
recommendation, SMBv1 should be disabled on all servers of a domain. We made
this change on our all servers. After some days, we found that we are not able
to RDP into the servers and we are not able to resolve their DNS hostname as well.
After digging into
the problem, I found that "NetLogon" Server was stopped. When I tried
to run it, it gave me error that one of its dependency service is stopped or
disabled. Later I found that it is because of "Workstation" service because
it was also in stopped mode. In event log I found that it is not able to run
because SMBv1 is disabled. Below are the screenshots which will show you what I
am talking about.

I was asked to help a client who recently created new domain controllers and removed the old ones. It included transfer of FSMO roles too. They were few issues which they were facing.
I was asked to help a client who recently created new domain controllers and removed the old ones. It included transfer of FSMO roles too. They were few issues which they were facing.
1. All clients were
getting different time zones.
2. Event IDs 50 on PDC
[The time service detected a time difference of greater than…]
3. Authentication was
stopped for some sites.
When I looked events
on PDC, then I found that root cause. NTP settings was not defined properly due
to which all these issues were there. It happened because they transferred PDC
role from old DCT to new DCT. Here are the steps which I followed and it was
fixed after that.
