Improvements and fixes
This update addresses an issue where UI elements, including menu bars, are missing from Windows and Java applications running on computers with multiple monitors (multimon). The issue affects console and Remote Desktop logons when the main monitor is not in the top left area of the monitor layout in Control Panel. Applications may also stop responding or not work properly when moved between monitors.
This issue impacts the following releases:
- 2017-08 Monthly Rollup - KB4034664
- 2017-08 Security-only update - KB4034679
- 2017-08 Preview of Monthly Rollup - KB4034670
Known issues in this update
Due to a defect in WLDAP32.DLL, applications that perform LDAP referral chasing can consume too many dynamic TCP ports (potentially exhausting them) after installing KB4025337 and KB4025341. Applications and roles known to make these referrals may include Outlook.exe, DFSR, and others.
You may be experiencing this issue if restarting applications that perform LDAP referral chasing returns normal functionality on machines that installed KB4025337 and KB4025341.
To work around the problem, restart services or applications that perform LDAP referral chasing to free TCP dynamic ports. A reboot will also free ports. For example, restarting Outlook will free ports used by that application.
To work around the problem for cluster computers hosting the DFSR service, move the virtual cluster object to the Computers container to avoid reaching the referral chasing search, which leads to the dynamic port leak.Microsoft is working on a resolution and will provide an update in an upcoming release.
