Why do some room calendars refuse to synch in Outlook?

2013/02/04 plagwitz Leave a comment

Problem: I recently had to recreate ("Add calendar"/ "From address book") my calendar tree (groups) in Outlook 2010, and now I notice that
1. while other room calendars do not (e.g. LRCRoomCOED433b).
The offending calendars can be loaded from internet (being published – with limited details, so that is not a real workaround): e.g. “ITL up t to 2201”.
In the Properties/ Permissions, I can see that for some calendars that synch, I am not listed as Editor (presumably being more than that? Owner?) – but not all calendars that synch (e.g. LRCRoomCOED433b) have this as a requirement.
Is there maybe a limit of how many calendars can be loaded in Outlook at any given time?
Impersonating the calendar and sharing it with myself does not help either:

In the settings below (albeit a year old), I cannot see a substantial difference either:

Multilingual WordNet search interface

Covers a subset of the languages supported by the LRC. Based on Wordnet which is rather than a dictionary for human consumption, a machine-readable semantic network, but here is one of its machine-generated applications.

How to check for “lost trust” issues on LRC PCs before classes

2013/01/31 plagwitz Leave a comment

We experience computers that fail allowing students to log in, thus disrupting face-to-face classes in the LRC.

We have found no diagnostic tool working, other than attempting to log into the machine.
Current workaround is manually removing and adding them back to the domain, when students experience login issues – which is time consuming, certainly too time-consuming during classes.

Suggested workaround Checklist, to be run before any class in the LRC (check calendar):
1. Student staff
  1. logs in on each individual computer and notes failures (
  2. this could be accelerated by using mstsc, especially with remote desktop connection manager and lrc.rdg) on the reception desk computers
  3. do we have automated (scriptable) login options?
2. Coordinator
  1. from Deepfreeze-console, unfreezes computers in question
  2. from Symantec Ghost Console
    1. puts computers in question into domain-issues folder
    2. runs tasks against this folder
      1. “remove from domain”
      2. “add to Domain&AD”
  3. from Deepfreeze-console, freezes computers in question

Copy/paste meetings with resource mailboxes in Outlook on MS-Exchange 2010?

2013/01/31 plagwitz Leave a comment

For schedules too complex to be managed in the repeating dialogue, why can I, in Outlook calendar, copy/paste meeting requests that include rooms into a new time slot, but while the new meeting appears immediately in my calendar, no update gets sent to the room unless I open the new meeting and click the button: “send” manually:

How you can fix student homework “file save errors” on Sanako Study 1200 and Windows XP

2013/01/30 plagwitz Leave a comment

Background: We recently got our Sanako network share permissions set up to vendor specifications, and the privileges tightened up appropriately. Fortunately, in the process of this, I was warned to make sure Windows XP has the registry key set: MoveSecurityAttributes, as otherwise XP does not update the permissions when moving files between folders:
Symptom: Here is how this seems to have played out with Sanako ”homework” files (which get sent from the teacher to the student for writing and submitted back), specifically with files that I had:
1. uploaded from my office PC (XP without the MoveSecurityAttributes key) to the Sanako teacher share
2. tried to deploy as homework from the Sanako Study 1200 teacher station (also XP without the MoveSecurityAttributes key), resulting in a “file save” error:
3. Additional context:
  1. sending files to students failed, but not to teachers;
  2. student had not run out of file space on the network share;
  3. students did not lack permissions to the Sanako network share in general;
  4. we did not run into issues with Sanako exam audio recordings which are sent from the student PCs to the network share.
4. Resolution:
  1. adding HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\MoveSecurityAttributes, DWORD ,1, to the computer the files originates from:
    1. first the office pc: this did not fix the issue.
    2. then the teacher PC: this seems to have fixed the issue:
    3. Here is hoping that this can fix your “file save”error also.
Update: Also consult Raymond Chen’s "Wait, so does moving a file recalculate inherited permissions or doesn’t it?", and the hearty discussion that ensued.
