In DRA, do not use the backslash “\” character in single form as any part of an object name when performing operations on objects in DRA PowerShell, it will produce an error. Use two backslashes in sequence to avoid an error. Here is an example:
Get-DRAContact -Domain 'dom010250.lab' -IgnoreCertificateErrors -Identifier 'CN=Vijay\\Contact,OU=Vijay,DC=dom010250,DC=lab' (Gets the contact with name 'Vijay\Contact')
