[Read more…] about August Windows Server PatchingRetiring Windows Internet Naming Service (WINS)
Windows Internet Name Service (WINS) is a legacy computer name registration and resolution service from Microsoft that maps computer NetBIOS names to IP addresses, and is implemented on our network with the machines wins1.eecs.berkeley.edu and wins2.eecs.berkeley.edu. Computers generally use DNS (Domain Name System) now, and most organizations stopped using WINS years ago.
We are planning to (finally) retire this legacy service on the following schedule:
- Tuesday, August 8: remove configuration of WINS servers from EECS Domain Controllers, and from our NetApp fileservers. We don’t think any clients should notice this change, but we’ll be on the lookout for any issues that come up.
- Tuesday, August 15: update DHCP to no longer specify WINS servers to DHCP clients. DHCP clients should have their network info updated over the next day or so, but will continue to resolve hostnames via DNS. So in general, we expect clients should notice no change. However, if your Windows client is relying on a shared Windows resource from a machine without a fixed IP name (for example, a shared lab printer attached to a Windows PC), you may lose access to that resource. Access to home.eecs, project.eecs, and printers on print.eecs will not be affected.
- September 1-30: We will monitor any remaining WINS client traffic to wins1.eecs and wins2.eecs, and attempt to notify registered sysadmins to update clients accordingly.
- Tuesday, October 3: turn off WINS.
We expect few people to be affected by the retirement of WINS, but if you do have a problem after one of the changes, feel free to contact the Helpdesk with any details.
July Windows Server Patching
Microsoft will release their patches for the month on Tuesday, July 11th, 2023. PRINT, WINTERM and WDS will automatically patch and reboot Wednesday, July 12th, at 3:00 am.
WINTERM may be unavailable till 10:00 am Wednesday, July 12th, depending on additional software updates.
[Read more…] about July Windows Server PatchingUrgent NetApp Fileserver Downtime, Saturday July 8, 2023
We will be scheduling an urgent 4 hour Maintenance to update our NetApp fileserver from 8am to 12pm on Saturday, July 8, 2023. This update must be done prior to installing Microsoft Updates on AD Domain Controllers scheduled for release on Jul 11th to secure the Netapp and maintain future connectivity with Microsoft AD Domain connection for our CIFS/SMB Shares.
All Home directories and Project shares (CIFS/SMB and NFS) may experience disconnection during the update that may cause data loss on active, open files. Please close your open files and save them before Saturday Morning. Services (e.g. webservice) that depend on this storage will also be down or unresponsive.
When maintenance is completed, NFS clients should automatically resume normal operation, but a reboot should help if they don’t. CIFS clients (such as Windows and MacOS) may need to remount filesystems, or simply be rebooted.
