RequestContentFromCAS RequestContent failed 0x87d01201

While testing an SCCM application deployment, I noticed RequestContentFromCAS RequestContent failed 0x87d01201 error. Let’s look at why this issue occurs and how to fix it.

I was testing a package that uninstalls the Office 365 from client machine. However it immediately failed when I attempted to install it.

The software center showed unable to make changes to your software error 0x87d01201. There wasn’t any issue with the package rather it was something that had to do with disk space on the client machine.

Reviewing the execmgr.log file on the client computer showed RequestContentFromCAS RequestContent failed 0x87d01201 error.

RequestContentFromCAS RequestContent failed 0x87d01201

The RequestContentFromCAS Request Content failed 0x87d01201 error comes up on client machine where there isn’t enough disk space. Hence the client fails to download the content.

The error 0x87d01201 translates to the content download failure because there is not enough available space in cache or the disk is full.

When you install SCCM client agent, by default the client cache size is set to 5120 MB. However you can configure Client Cache Settings in SCCM and change or modify the client cache size.

Manually Increase the Client Cache Size

You can either increase the client cache size from SCCM server or modify it manually on the client machine. To manually increase the client cache size on a machine, follow these steps.

On the client computer, go to control panel and open Configuration Manager. Under the Configuration manager properties, click Cache tab. Click Configure Settings and increase the client cache size. Click OK.

Modify Client Cache Size Using Client Settings

To increase the client cache from SCCM server on all machines, follow the below steps.

• Launch Configuration Manager console
• Go to Administration\Overview\Client Settings.
• You can either edit the default client settings or create a new custom setting.
• Edit the client settings and click Client Cache Settings.
• Under Device Settings, set Configure client cache size to Yes.
• Configure the Maximum cache size (MB).

After I increased the client cache size, the package download was successful.
