There’s nothing worse than needing to get console access on a physical server because of a problem that is preventing you from accessing it via PowerShell Remoting, Remote Desktop, SSH, or some other remote access protocol. As it turns out, there is something worse: getting errors on the embedded remote management card.
If you’re using the integrated Dell Remote Access Controller (iDRAC) as part of your server management, you may encounter an iDRAC screen with the word “undefined” repeated over and over, along with the “The webpage cannot be found” error, in Internet Explorer 11. I’ve seen the error on both iDRAC 6 and iDRAC 7:
Depending on the iDRAC version you have, there are a few different workarounds, as well as one fix if you’re running version 7.
Upgrade the firmware
If you’re running iDRAC 7, you can install a firmware update that will fix the problem permanently. Dell has a page for iDRAC 7 that lists the current firmware builds along with download links. The 18.104.22.168 build that was released in April 2015 (the latest build as of the writing of this article) fixes the problem. The biggest gotcha with upgrading the firmware in this solution is checking to see if the latest iDRAC firmware breaks anything for you or requires you to update other infrastructure. Additionally, if you have to go through change control to make an update to the iDRAC firmware, this may not be the quickest solution to your problem.
For the Dell iDRAC 6, earlier versions of Internet Explorer and some older versions of Firefox are supported. If you have a machine with an older build of IE, you can switch to that system. I was also able to access an iDRAC 6 with more modern versions of Firefox.
Use Internet Explorer Enterprise Mode (EMIE)
Like many other web applications, the Dell iDRAC web interface can be put into Enterprise Mode and fooled into thinking it is running in IE8. Just be aware that if you manually enable Enterprise Mode by going to Tools > Enterprise Mode, you’ll be kicked out of the iDRAC interface and have to log back in.
If the Tools > Enterprise Mode option is missing in IE11, you most likely don’t have Enterprise Mode enabled. You can enable EMIE in Group Policy or enable it by making a Registry edit. Open the Registry editor and browse to HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Internet Explorer\. You’ll need to add additional keys by right-clicking the Internet Explorer key and choosing New > Key. The finished structure should be HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Internet Explorer\Main\EnterpriseMode. Last, right-click in the right pane and choose New > String Value and type Enable. Your finished product should look something like this:
Enable Enterprise Mode for Inter Explorer in the Registry
Restart Internet Explorer. You should now be able to enable Enterprise Mode on your iDRAC to remotely manage your server.
