### Domain Enumeration

Current domain name:

```
PS C:> [System.Net.Dns]::GetHostByName(($env:computerName))
PS C:> [System.DirectoryServices.ActiveDirectory.Domain]::GetCurrentDomain()
```

### Domain Forest Trusts

```
PS C:> ([System.DirectoryServices.ActiveDirectory.Domain]::GetCurrentDomain()).GetAllTrustRelationships()
PS C:> ([System.DirectoryServices.ActiveDirectory.Forest]::GetCurrentForest())
PS C:> ([ADSISearcher]"(objectClass=trustedDomain)").FindAll()
PS C:> ([ADSISearcher]"(objectClass=trustedDomain)").FindAll() | %{$a=$_.Properties["trustattributes"]; $d=$_.Properties["trustdirection"]; $t=$_.Properties["trusttype"] ; write-Host $_.Properties["distinguishedname"] $a $d $t}
```

### Get Password Policy

```
PS C:> Get-ADDefaultDomainPasswordPolicy -Current LoggedOnUser
```

### Get a Domain Computer

```
PS C:> ([ADSISearcher]"(&(objectClass=computer)(name=SV-*))").FindAll()
```

The above one-liner we searched for a computer name starting with “SV-”, that can possibly be a server appellation. Similarly, it is possible to enumerate a specific computer with the exact name.

```
PS C:> ([ADSISearcher]"(&(objectClass=computer)(name=<COMPUTERNAME>))").FindAll()
```

### Get All Domain Computers

```
PS C:> ([ADSISearcher]"ObjectClass=computer").FindAll()
```

### Enumerate Single User

```
PS C:> ([ADSISearcher]"(&(objectClass=user)(samAccountType=805306368)(samaccountname=<USERNAME>))").FindAll().Properties
```

### Enumerate All Domain Controllers

```
PS C:> ([ADSISearcher]"(&(objectCategory=computer)(userAccountControl:1.2.840.113556.1.4.803:=8192))").FindAll()
```

### Enumerate All Users

```
PS C:> ([ADSISearcher]"(&(objectClass=user (samAccountType=805306368))").FindAll()|ft
```

### Enumerate All Users With Specific Properties

Filter by property, this code will just display “samaccountname” as a result for all users.

```
PS C:> ([ADSISearcher]"(&(objectClass=user)(samAccountType=805306368))").FindAll() | %{ $_.Properties["samaccountname"] }
```

### Enumerate all users with a SPN

A service instance’s service principal name (SPN) is a unique identifier. Kerberos authentication uses SPNs to link a service instance to a service login account. This enables a client application to ask the service to authenticate an account even if it doesn’t know the account name.\
If we want to display all users with SPN then we can use below code:

```
PS C:> ([ADSISearcher]"(&(objectClass=user)(servicePrincipalName=*)(samAccountType=805306368))").FindAll()
```

### Enumerate a Domain Group

```
PS C:> ([ADSISearcher]"(&(ObjectClass=group)(samaccountname=Domain Admins))").FindOne()
```

### Enumerate All Domain Groups

```
PS C:> ([ADSISearcher]"ObjectClass=group").FindAll()
```

### Enumerate domain group members

```
PS C:> ([ADSISearcher]"(distinguishedname=CN=AB ACCESS,CN=Users,DC=corp,DC=manmeetdc,DC=local)").FindOne().Properties.member
```
