Cannot open your default e-mail folders.

I'm having this problem for two days. One of the users in the remote site cannot use her Outlook 2007 and she's getting this error message in the PC that she's using. She's connected to the MS Exchange 2007 located in the main site through VPN. By the way, VPN connection is connected perfectly. I connected to her system by means of a remote software. Her Outlook is completely appearing disconnected. It seems that the Exchange Server cannot resolve the username of that use.So I decided to go to the remote office and setup 
her email on my laptop but is running smoothly. I configured it easily without experiencing any problem.

So I created a new profile for the Outlook and I get this error:


"Cannot open your default e-mail folders. The file C:\Documents and Settings\USERNAME.DOMAIN\
Local Settings\Application Data\Microsoft\Outlook\outlook.ost cannot be accessed. You must connect to your Microsoft Exchange Server computer at least once before you can use your offline folder file."


To fix this problem, here are the steps that I took:
1. Open Control Panel - Mail
2. Create a new profile
3. Specify the Microsoft Exchange server or the FQDN
4. Put the username or the name of the user 
5. Dont click on the check name tab, instead go to More Settings >Security  and put the tick mark on encryption and click Apply.
6. Now you can click on the "Check Name" and now it will resolve the name.

Hope this helps!
Good luck!

Leased Line Configuration- Cisco 2900 Series Router

One of our clients decided to upgrade their Leased Line connection from 2Mbps to 8Mbps and bought Cisco 2900 Series Integrated Services Router. I was asked to configure which in the beginning I had some troubles in the configuration but later on, I finally made it working.

Below are the commands and configurations I had gone through to make it work.


*Setting up hostname and DHCP server
Router> en
Router#conf t
Router(config)# hostname HOTEL
HOTEL(config)#ip dhcp pool mypool
HOTEL(dhcp-config)#network 192.168.2.0 255.255.255.0
HOTEL(dhcp-config)#dns-server 213.42.20.20 195.22.241.222
HOTEL(dhcp-config)#default-router 192.168.2.1
HOTEL(dhcp-config)#ip name-server 213.42.20.20
HOTEL(dhcp-config)# exit


*Configure GigabitEthernet 0/0 for connection to the ISP public address which they  subscribed
HOTEL#conf t
HOTEL(config)# int GigabitEthernet 0/0
HOTEL(config-if)#ip add 83.111.95.77 255.255.255.252
HOTEL(config-if)#no shut
HOTEL(config-if)# ip nat outside
HOTEL(config-if)#exit


*Configure GigabitEthernet 0/1 for your LAN
HOTEL#conf t
HOTEL(config)# int GigabitEthernet 0/1
HOTEL(config-if)#ip add 192.168.2.1 255.255.255.0
HOTEL(config-if)#no shut
HOTEL(config-if)#ip nat inside
HOTEL(config-if)#exit
HOTEL(config)#


*Configure the Access-list
HOTEL(config)#ip nat inside source list 100 interface GigabitEthernet0/0 overload
HOTEL(config)#access-list 100 permit ip any any
HOTEL(config)#ip route 0.0.0.0 0.0.0.0 83.111.95.77
HOTEL(config)#exit
HOTEL#copy run start  <--- Save the configuration. Don't ever forget this command.

Goodluck!
