# Microsoft RDP protocol error

The Microsoft RDP protocol error disconnecting sessions in Remote Desktop Manager is fixed by disabling bitmap caching or renaming the default.rdp file.

`Because of a protocol error, this session will be disconnected. Please try connecting to the remote computer again.`

### Solution 1

1. In the properties of the RDP session, go to ***Common – General***.
2. Under the ***Experience*** tab, uncheck ***Persistent bitmap caching*** and ***Visual styles***.
3. Click ***OK*** at the bottom to save your changes.

### Solution 2

1. Close Remote Desktop Manager
2. Rename the "default.rdp" file in ***My Documents*** to "default.old".
3. Restart Remote Desktop Manager and try to connect with RDP.

### Solution 3

1. Log into the target machine by directly going to the console of that server or by any tool, like VNC, so that we can get access to that machine.
2. Right-click on the Desktop.
3. Select the ***Properties***.
4. Dropdown the ***Themes*** and select another one than the current one.
5. Click on ***Apply***, then ***OK***.
6. Connect to the machine remotely.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.devolutions.net/rdm/knowledge-base/troubleshooting-articles/microsoft-rdp-protocol-error.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
