How does one disable Jumbo MTU packets on a NIC that has no disable option? Is there some type of command I can use to bypass the GUI option on a user machine? I think it might be causing network performance issues.

What exact NIC is this?  Typically jumbo frames are disabled by default.  The setting you are showing just shows what size of frame to use, if jumbo frames are enabled.

Then again, it could be the setting description indicates that the MTU can be made larger.
The current setting of 1500 is the ethernet default so this shouldn't be a problem.

As state by Frabble, 1500 is the default MTU and thus this setting should cause absolutely no network performance issues. A jumbo frame is just a packet with large MTU. Setting this to 1500 or lower should not cause a problem whether you have an option to disable or not.

Thanks! Knowing that helped me troubleshoot elsewhere, the culprit was Symantec network protection (no big surprise).
