Known issues in this update

Symptom |
Workaround |
|
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. If restarting applications that perform LDAP referral chasing returns normal functionality on machines that installed KB 4025337 and KB4025341, you may be experiencing this issue. |
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, place the virtual cluster object under 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. |

If a machine has more than one monitor connected and the screen numbering is not in sequence, some applications will experience rendering issues. |

The WordPad application can sometimes crash on launch after installing KB4025341. |
Microsoft is working on a resolution and will provide an update in an upcoming release. |
