Hello all

Today I earned another Cisco certificate. It’s CCDA. I had 1000 points out of 1000 🙂

I played with HP Procurve switches and I found one weird default setting. Spanning Tree Protocol is disabled by default. It was weird finding because I tried to interconnect two switches with pair of cables whole my network went down 🙂 It was overloaded with b-cast storm.

Today I was facing weird problem at our customer. They have IBM HS21 blade server with build-in dual-port Broadcom network card. There was only Windows 2008 installed with all up2date drivers. Everything worked fine besides network performance. Upload from server to other servers was around 20MBps, which is fine. Problem was download to server, because it was 1-2MBps.

Na martinskom danovom urade som bol odniest tlacivo na 2% z dane pre skolku, kde chodi nas Risko. Ked som dosiel, tak ma na “Miestnosti prveho kontaktu” nasiel papierik s otvaracimi hodinami, ktorym som na prvy uponahlany pohlad pochopil uplne opacne ako boli pisane. Vsak pozrite sa sami:

Ja som to pochopil na prvy uponahlany pohlad, ze maju otvorene len v Utorok a vo Stvrtok, ale opak je iny. Tato miestnost je otvorena len v nestankove dni (ked cely danovy urad spracuvava papiere) a to je v uvedenych hodinach. Toto vysvetlenie som dostal od veducej oddelenia daneho danoveho uradu.

Este, ze ti uradnici rozumeju tomu co napisu 🙂

Hello

Problem: Today I’ve played with IGEL thin client. It was set up to automatically log-in to Windows OS. When I tried “Log off” from sessions it logged me in again. Another problem was that it logged me in under “user” account, so I couldn’t change any setting.

Hello all again

So we will write in english since now.

Takže po dlhšej dobe som zase narazil na veľký problém. Implementoval som Exchange 2007 a chceli sme dosiahnuť, aby používatelia, ktorí sa prihlasia na OWA rozhranie mali vždy nastavenú login stránku na slovenský jazyk. Taktiež sme chceli dosiahnúť, aby mali všetci používatelia svoje mailboxy v slovenskom jazyku.

Určite sa aj vám stalo, že ste vybrali zariadenie z počítača a už ste nemohli nájsť zariadenie v správcovi zariadení. Da sa manuálne v správcovi zariadení zapnúť, aby bolo možné vidieť tzv. Hidden devices. Ale štandardne vie správca zariadení zobraziť len non-Plug and Play zariadenia, ovládače a tlačiarne.
