Azure VM CMD & PowerShell from the Portal

Azure VM CMD & PowerShell from the Portal Today I was trying to troubleshoot an Azure VM. This VM is behind a Network Virtual Appliance (NVA) and at the subnet it has User Defined Routes (UDR) that routes the traffic to the NVA. We was troubleshooting the NVA and it was not possible to connect with RDP to the VM. Serial Console This is an excellent scenario to use the Serial Console. From the Azure Portal, portal.azure.com, navigate to the Azure VMs blade, scroll down to the Support + Troubl

Create Azure File Shares at your ARM template using PowerShell

Create Azure File Shares at your ARM template using PowerShell Using Azure Resource Manage template deployment, you can create a Storage account but you cannot create File Shares. Azure File Shares can be created using the Azure Portal, the Azure PowerShell or the Azure Cli. Mainly, the idea is to run a PowerShell script that will create the File Shares. This script will be invoked inside the ARM Template. In order to use a PowerShell script from a template, the script must be called from a URL.

Serverless Computing | Check your expired public certificates

Connect two or more Azure Virtual Networks using one VPN Gateway Peering is a feature that allows to connect two or more virtual networks and act as one bigger network. At this post we will see how we can connect two Azure Virtual Networks, using peering and access the whole network using one VPN Gateway. We can connect Virtual Networks despite if they are in the same Subscription or not. I have created a diagram to help understand the topology. We have a Virtual Network with Site-2-Site VPN w

Azure App Service, get data from on-premises databases securely

Azure App Service, get data from on-premises databases securely There are many scenarios where we want to have the Web Application on the Cloud but on the other hand, due to various limitations, the database stays on-premises. Azure has a service, called Azure Hybrid Connections, that allows the Web App to connect to on-premises databases, using internal IP address or the database server host name, without a complex VPN setup.

How to disconnect a mailbox & re-assign it to new user in a Hybrid Scenario

How to disconnect a mailbox & re-assign it to new user in a Hybrid Scenario Scenario objectives: We have an Exchange Hybrid setup between on-premises and Exchange Online (Office 365). All users are synced and the mailbox is located at Exchange Online. We need to separate an existing mailbox from its user account and re-connect this mailbox to a new user account. If the mailbox in this scenario was located at the on-premises Exchange it would be an easy process just using the Exchange Managem

Reserve external IP on Azure Cloud Service

When we create a VM on Azure, at the same time we create a Cloud Service. Later we can create more VMs on the same cloud service. Each cloud service has a unique Public IP. For as long the Cloud Service has at least one VS running this Public IP remains the same. If all VMs of a Cloud Service are off then the Public IP is released and next time the VM is powered on it will take a new Public IP.   Using PowerShell we can reserve a Public IP for as long as the Cloud Service exists, with or witho

Exchange 2010 & Hbrid Wizard troubleshooooting

Καλησπέρα στην κοινότητα. Θέλω να μοιραστώ μαζί σας τα προβλήματα που αντιμετώπισα σήμερα σε ένα Hybrid Configuration με Exchange 2010 SP3 UR6. Δεν είναι κάτι τραγικό, ούτε κάτι που δεν έχουμε αντιμετωπίσει στο παρελθόν αλλά πιστεύω ότι όσο μοιραζόμαστε τόσο μαθαίνουμε.   Παραλείπω τα αρχικά, Domain verification, DirSync, Certificate request, το Outlook Anywhere ενεργό, όλα τα virtual directories φαίνονται μια χαρά, telnet 443 μια χαρά, OWA μια χαρά, γενικώς καλά και φτάνω στο Hybrid Wizard.

Remove/Add Microsoft Antimalware Service from an Azure VM

Microsoft offers for free it’s antimalware service. When you create a new VM you have the option to enable it. This will install the System Center Endpoint Protection client to the VM managed by Azure. If you have added this but now you want to remove it and add some other antivirus/antimalware solution you cannot do it by just uninstalling the client from the VM. The client will auto re-insalled by Azure. There are two ways to completely uninstall the program and remove it from Azure. One is us

Azure Backup Email Notification

I was looking for a free solution to have an email notifications for Azure backup. After reading other blogs and technet site I end up to use PowerShell Send-MailMessage attached to the Azure Backup Logs. In short, when the Azure Backup log is created, the script lists the last 2 days events, creates an html file and mails the report with the html as attachment to you.   First find the Azure backup Event Log, it under “Applications and Services Logs, CloudBackup, Operational” and select to att

Create a Disk in specific Storage Account and Attach it to a VM in Azure

There are many reasons to have your Disks stored at separate Storage Accounts, per Cloud Service. One is that a Storage Account in Azure provides 20000 IOPS and every disk in Standard Tier 500 IOPS. Azure support suggests to don’t have more than 40 disks per Storage Account. Also you may want to have your disks lined (go to Azure, Cloud Services, selsect a Cloud Service and you can see the “Lined Resources” tab, there you can link storage accounts to the Cloud Service) to the same Cloud Services

Set Static Private IP to an Azure VM

First of all, the VM must be within a virtual network to be able to add a static Private IP address   There are two ways to set a static private IP. One is using the new Azure Portal "portal.azure.com" and one via PowerShell.   Using the new Portal, browse a VM, select settings and then IP addresses. There at the Private IP address you can select "Static" and add the IP address.   Using PowerShell, first connect to the Azure (details on this post), and use the following commands:   #Test
