Replace Group Attribute "Description" and "Info"

Hi.

I have several houndreds of groups where description and info fields are empty or false. Therefore, I'm trying to create script that can automate the following for me, however I cannot put it together:

1) Replace Description and Info

2) Create log in c:\logs

3) I have to do it in 3 domains in the same forest, however I do not know how to make the script search in 3 domains. I can reach them all by -server domain1, -server domain2, -server domain3

Sample of txt-file:

SamAccountName,Description,Owner
CRITest,This is an test description,Owner: SIK/CRI`r`nAccess: Sales Dept.

My script so far:

# Import AD Module            
Import-Module ActiveDirectory           
           
# Import CSV into variable $fdigroups           
#$fdigroups = import-csv "c:\fdigroups.csv"           
$groups = Import-Csv -Path "c:\fdigroups.csv" -Delimiter "," -Encoding "UTF8"          
# Loop through CSV and update groups if name like groupname in CVS file           
           
foreach ($group in $groups) {           
#Search in specified Server and Update existing attributes           
 Get-ADGroup -Filter {Name -like "$($Group.samaccountname)"} -server mgt000t -Properties * -SearchBase "ou=Groups,DC=domain,DC=net" |
 Set-ADGroup -Description $($Group.Description) -Replace @{info=$group.Owner}
}

Can anyone help me to get this working?

Regards

Carsten
