Excel VBA kullanarak Active Directory Kimlik Doğrulama

[mehmetyildizz]

Merhabalar

Hazırlamakta olduğum bir excel dosyası için açılışta şirketin domain server ından yani active directory den kimlik doğrulaması (Active Directory Authentication) yapmasını istiyorum.
Bir çok sitede araştırdım fakat çok anlaşılır bir döküman bulamadım, bulduğum bir kod örneğini aşağıda veriyorum. Bu kodu kendime göre yorumlayamadım, yani şirket server adını nereye yazacağım yada başka neler eklemem gerekir bilemedim.
Ayrıca bu kodlar eklediğim herhangi bir excel dosyasında ilk satır da hata veriyor.

Bu konuda yardımlarınızı bekliyorum.

Teşekkürler
İyi çalışmalar
