On Friday, 14.3.2025, the monthly Windows Updates will be released. Please install them on your DESY Windows devices as soon as possible to ensure that they are up-to-date and secure.

To do this, connect your Windows device to the internal DESY network after the updates have been released. Use VPN if you are extern. When prompted or at the end of the day, restart or shut down your Windows device.

Seven days after the release of the updates, a forced restart of the computers will take place if this has not taken place in the meantime.

Maintenance caused by: Windows updates and the monthly maintenance work on the corresponding central computers

The maintenance has been finished.

Due to technical problems that could not be clarified beyond doubt before the maintenance, the XWiki version update has been postponed at short notice on the recommendation of the manufacturer.

The problem is solved since Tuesday, 27.05.2025.

-----------------

Since Tuesday, 01.04.2025, cross-service login via the central authentication service Keycloak does not work as usual.

Normally, logging in once is enough to access multiple services. At the moment, however, this is not possible:
For example, if you log in at https://mail.desy.de or https://xwiki.desy.de, you are not automatically logged in to other services that also use Keycloak.
Currently you need to log in again for each of these other services.

The following web services are affected:

- Indico (https://indico.desy.de)
- DESY Sync & Share (https://syncandshare.desy.de)
- DESY Mail (https://mail.desy.de)
- XWiki (https://xwiki.desy.de)
- Jupyterhub (max-hub and naf-jhub)

We are working on a solution to this problem.

Caused by; Bug in the Login Service (Keycloak)

The web client (https://rdsweb.desy.de/rdweb/webclient) for the terminal server has received a new certificate.

As a side effect some users may receive an error message about an unexpected certificate when connecting to a specific terminal server.

In this case the users should delete their browser cookies.

Starting immediately, VPN connections from outside to the internal data network can be established using the VPN service "eduVPN" also from non-DESY devices. eduVPN allows access to internal websites as well as the establishment of Remote Desktop connections (RDP) to Windows devices and SSH connections to Linux devices within the internal data network.

Please note that for using eduVPN, it may be necessary to first enable the IP address of your device via https://it-access.desy.de. This process is fully automated and takes only a few minutes after a single click. You can find more information in the eduVPN documentation:
https://it.desy.de/dienste/netzwerke/vpn/eduvpn

For connecting to DESY devices, Cisco VPN should still be used, as it is required for, among other things, operating system updates and connecting to Windows network drives (H/N/S).

A comparison of the two types of VPN connections (eduVPN vs. Cisco VPN) can be found on the following website:
https://it.desy.de/dienste/netzwerke/vpn

On Monday, 16.06.2025, the previous printer service v02spool of the Windows terminal server winsaphr[1] will be switched off.

If you only print from winsaphr using the SAP GUI or not at all, you can ignore this information.

If you print from winsaphr from other applications, please carry out a one-time reinstallation of the printer (hr[printer name]) previously used on winsaphr. To do this, please use the new printer service v02spool11.

Instructions for installing new printers on winsaphr can be found on the Desktop of winsaphr or on the following website:
https://it.desy.de/sites2009/site_it/content/e5/e304616/e304647/infoboxContent304649/winsaphr-Druckerinstallation-2025_ger.pdf

If you have any questions, please contact v2hr-support@desy.de

[1] The Windows terminal server winsaphr is used for accessing SAP/HCM, shift planning and exchanging data with V2.

As already announced in the CUC, the Big Blue Button video conferencing software (https://conf.desy.de) will be shut down at the beginning of May 2025.

Users who require video conferencing service should use ZOOM or DFNConf. Information about these services can be found on the following website:

Since the last update of the Cisco Secure Client for vpn.desy.de <http://vpn.desy.de/> on 7.3.2025, the behaviour of the software has changed.

It can happen that the previously pre-filled “vpn.desy.de <http://vpn.desy.de/>” disappears in the login window of the program. Previously, the Cisco VPN software “remembered” the settings. Since the update to more recent versions, vpn.desy.de <http://vpn.desy.de/> sometimes has to be entered again.
