If you are unable to drop the **distribution** database in SQL Server, there are a few things to check:

### 1. Ensure There Are No Active Replication Components
Before you can drop the distribution database, make sure that **replication** has been completely removed.

Run the following commands to check if replication is still configured:

#### **Check if the server is acting as a distributor:**
```sql
EXEC sp_get_distributor;
```

#### **Check for active publications:**
```sql
EXEC sp_helppublication;
EXEC sp_helppublication_snapshot;
```

#### **Check for active subscriptions:**
```sql
EXEC sp_helpsubscription;
```

#### **Check for active distribution agents:**
```sql
EXEC sp_helpreplicationdb;
```

---

### 2. Remove All Replication Components

If replication is still active, follow these steps:

#### **(a) Remove all subscriptions**
```sql
EXEC sp_dropsubscription @publication = 'ALL', @subscriber = 'ALL', @article = 'ALL';
```

#### **(b) Remove all publications**
```sql
EXEC sp_droppublication @publication = 'YourPublicationName';
```
Repeat for each publication.

#### **(c) Disable publishing and distribution**
```sql
EXEC sp_replicationdboption @dbname = 'YourDatabaseName', @optname = 'publish', @value = 'false';
```

#### **(d) Drop the Distributor**
```sql
EXEC sp_dropdistributor @no_checks = 1, @ignore_distributor = 1;
```

---

### 3. Try Dropping the Distribution Database Again
Now, try dropping the distribution database:

```sql
USE master;
ALTER DATABASE distribution SET SINGLE_USER WITH ROLLBACK IMMEDIATE;
DROP DATABASE distribution;
```

If you still cannot drop it, check for active connections:

```sql
SELECT * FROM sys.dm_exec_sessions WHERE database_id = DB_ID('distribution');
```
Kill any active connections using:

```sql
KILL <SPID>;  -- Replace <SPID> with the session IDs found above
```

---

### 4. Remove Distribution Manually (If Needed)
If SQL Server still refuses to drop the distribution database:

1. **Manually delete the database files:**
   - Run `sp_helpfile` in the `distribution` database to find the MDF and LDF file locations.
   - Manually delete those files from disk after stopping SQL Server.

2. **Use `sp_configure` to disable replication completely:**
   ```sql
   EXEC sp_configure 'show advanced options', 1;
   RECONFIGURE;
   EXEC sp_configure 'allow updates', 1;
   RECONFIGURE;
   ```

3. **Restart SQL Server and try again.**
