Resolution
Directory and Resource Administrator 7.5
symptom
Error: "Unable to get default proxy strings from server. An invalid Active Directory pathname was passed."
symptom
Error received when attempting to set a new proxy generation rule.
cause
When you are setting the proxy email address rules in the Delegation and Configuration console, this error can occur if the value specified for GcServer under HKEY_LOCAL_MACHINE > SOFTWARE > Mission Critical Software > OnePoint > Administration > Modules > Accounts > Domains.Dns > YourDomain
is not actually a Global Catalog server or the specified Global Catalog server is experiencing connectivity issues.
fix
Until you resolve this error, you cannot add SMTP email addresses to default proxies for email address rules.
To fix the issue, ensure the GcServer value under HKEY_LOCAL_MACHINE > SOFTWARE > Mission Critical Software > OnePoint > Administration > Modules > Accounts > Domains.Dns > YourDomain
specifies a valid and functioning Global Catalog server.
