Fix Fill & Sign and Comment Tools Unavailable in Acrobat Reader on a Server
Question details
The user needs to enable and use the Fill & Sign and Comment tools in Adobe Acrobat Reader DC while working in a terminal server environment.

- Product
- Adobe Acrobat Reader DC
- Device & OS
- Windows Server 2016
- Scenario
- Attempting to annotate and sign PDF documents using Acrobat Reader DC deployed on a remote terminal server.
- Observed behavior
- The Fill & Sign and Comment tools are completely unavailable or cannot be selected on the Windows Server 2016 terminal server, even though these identical tools function perfectly on local desktop installations and in Acrobat Pro DC.
Ensure you have administrator privileges on the Windows Server 2016 terminal server to modify deployment settings, and verify that the current version of Acrobat Reader deployed matches the working local desktop version.
Repair and Update the Acrobat Reader Installation
Terminal server deployments can sometimes experience corrupted files or outdated patches that restrict specific tools. A quick repair and update can restore missing functionality.
In enterprise server environments, background updates or user profile corruptions can cause features like Fill & Sign to disappear. Running the built-in repair tool ensures all deployment files and feature modules are properly registered in the server environment.
Log into the Windows Server 2016 as an administrator. Open Adobe Acrobat Reader DC, click on the 'Help' menu at the top, and select 'Check for Updates' to install the latest patches.
Once updated, go back to the 'Help' menu and click on 'Repair Installation'. Follow the on-screen prompts to allow the wizard to fix any missing components.
Restart the terminal server session and open a standard PDF file to verify if the Fill & Sign and Comment tools are now available.

Verify Registry and Deployment Policy Settings
Enterprise Group Policies or registry configurations set via the Adobe Customization Wizard may be actively suppressing signing and commenting features.
Contact Enterprise Support
If standard local troubleshooting fails to unlock the tools, the issue may be related to specific terminal server licensing restrictions or known deployment bugs requiring vendor intervention.
Use WPS Office to Fill, Sign, and Comment on PDFs

- 1. Install WPS Office: Download and install the lightweight WPS Office suite onto your workstation or server environment.
- 2. Open your PDF file: Launch WPS PDF and open the document you need to annotate or sign.
- 3. Access Comment tools: Navigate to the 'Comment' tab on the top ribbon to easily add notes, highlights, and text boxes.
- 4. Fill and Sign the document: Switch to the 'Fill & Sign' tab to input form data and insert your digital or graphical signature.

Frequently Asked Questions
Why is the Fill & Sign tool grayed out in Acrobat Reader?
The Fill & Sign tool typically grays out if the PDF document contains security restrictions that prevent modifications. It can also happen on servers if a Group Policy or registry setting explicitly disables the feature.
Do I need Acrobat Pro to use Fill & Sign on a Windows Server?
No, the standard Fill & Sign and Comment features are included in the free version of Acrobat Reader DC. However, terminal server environments often have specific deployment policies that might restrict these free features by default.
How do I check if my PDF document restricts commenting or signing?
Open the PDF file, navigate to 'File' > 'Properties', and click on the 'Security' tab. Check the 'Document Restrictions Summary' to see if 'Commenting' or 'Signing' is labeled as 'Not Allowed'.
