It allows Windows to connect to external storage arrays and Storage Area Networks (SANs).

Standard File Location

The legitimate file is located in the following system directories:

How to Fix iscsidsc.dll Errors (Without Downloading)

If you are experiencing crashes, missing file prompts, or errors related to iscsidsc.dll, do not download individual DLL files from third-party websites. These downloads are often unsafe or outdated. Instead, use these built-in Windows repair mechanisms:

1. Run System File Checker (SFC)

The SFC tool scans all protected system files and replaces corrupted or missing files with a cached, healthy copy from the Windows operating system repository.

Press the Windows Key, type cmd.
Right-click Command Prompt and select Run as administrator.
Type the following command and press Enter:
```
sfc /scannow
```
Wait for the scan to reach 100%. Restart your computer afterward.

2. Run DISM Command

If SFC cannot fix the file, the Deployment Image Servicing and Management (DISM) tool will fetch fresh, official copies of corrupted files directly from Windows Update servers.

Open Command Prompt as an administrator.

Type the following command and press Enter:

DISM /Online /Cleanup-Image /RestoreHealth

Let the process finish completely (it may appear stuck at times). Restart your PC.

3. Re-register the DLL File

If the file exists but Windows fails to read it properly, re-registering it in the Windows registry can re-establish the connection.

Open Command Prompt as an administrator.
Type the following command and press Enter:
```
regsvr32 /u iscsidsc.dll
```
(This unregisters the file)
Type the following command and press Enter:
```
regsvr32 iscsidsc.dll
```
(This re-registers the file)

4. Restart the Microsoft iSCSI Initiator Service

Since this DLL belongs to the iSCSI infrastructure, restarting its parent service can clear temporary memory locks or glitches.

Press Win + R, type services.msc, and press Enter.
Scroll down and locate Microsoft iSCSI Initiator Service.
Right-click it and select Restart (or Start if it is not running).
Right-click it again, select Properties, and set the Startup type to Automatic.
